In this paper, a high gain low voltage low power Complementary Metal Oxide Semiconductor (CMOS) Low-noise Amplifier (LNA) using Chartered 0.18[Formula: see text][Formula: see text]m CMOS process for Ultra-wideband (UWB) receiver applications is presented. A novel multiple-feedback network constructed by the shunt feedback resistor with a transformer is adopted to realize desirable bandwidth extension and less chip area occupation in the common-source stage. All the cascaded transistors are configured by current-reuse structure and adjusted by forward body bias technique to further reduce supply voltage and power dissipation. The post-layout simulation results demonstrate that the proposed 3.4–10.1[Formula: see text]GHz UWB LNA accomplishes a maximum gain of 14.26[Formula: see text]dB with only 2.33[Formula: see text]mW power consumption at 0.8[Formula: see text]V supply voltage, while Noise Figure (NF) is 1.49–3.41[Formula: see text]dB and the chip area is 0.46[Formula: see text]mm2 including test pads (core area is 0.23[Formula: see text]mm2).

The paper presents a novel 5.15[Formula: see text]GHz–5.825[Formula: see text]GHz SiGe Bi-CMOS down-conversion mixer for WLAN 802.11a receiver. The architecture used is based on Gilbert cell mixer, the combination of MOS transistors and HBT BJT transistor device characteristics. The hetero-junction bipolar transistor (HBT) topology is adopted at the transconductance stage to improve power gain and reduce noise factor, and the LO series-parallel CMOS switch topology will be applied to reduce supply voltage and dc power at the switching stage. This mixer is implemented in TSMC 0.35-[Formula: see text]m SiGe Bi-CMOS process, and the chip size including the test pads is 1.175*0.843[Formula: see text]mm2. The main advantages for the proposed mixer are high conversion gain, a moderate linearity, low noise figure, and low power. The post-simulation results achieved are as follows: 14[Formula: see text]dB power conversion gain, [Formula: see text]6[Formula: see text]dBm input third-order intercept point (IIP3), 6.85[Formula: see text]dB double side band (DSB) noise figure. The total mixer current is about 1.54[Formula: see text]mA from 1.4[Formula: see text]V supply voltage including output buffer. The total dc power consumption is 2.15[Formula: see text]mW.

In this work, a low-power 0.18-μm CMOS low-noise amplifier (LNA) for MedRadio applications has been designed and verified. Cadence IC5 software with Silterra’s C18G CMOS Process Design Kit were used for all design and simulation work. This LNA utilizes complementary common-source current-reuse topology and subthreshold biasing to achieve low-power operation with simultaneous high gain and low noise figure. An active shunt feedback circuit is used as input matching network to provide a suitable input return loss. For test and measurement purpose, an output buffer was designed and integrated with this LNA. Inductorless design approach of this LNA, together with the use of MOSCAPs as capacitors, help to minimize the die size. On post-layout simulations with LNA die area of 0.06 mm2 and simulated total DC power consumption of 0.5 mW, all targeted specifications are met. The simulated gain, input return loss and noise figure of this LNA are 16.3 dB, 10.1 dB and 4.9 dB respectively throughout the MedRadio frequency range. For linearity, the simulated input-referred P1dB of this LNA is -26.7 dBm while its simulated IIP3 is -18.6 dBm. Overall, the post-layout simulated performance of this proposed LNA is fairly comparable to some current state-of-the-art LNAs for MedRadio applications. The small die area of this proposed LNA is a significant improvement in comparison to those of the previously reported MedRadio LNAs.

In this work, a new composite transistor cell using dynamic body bias technique is proposed. This cell is based on self cascode topology. The key attractive feature of the proposed cell is that body effect is utilized to realize asymmetric threshold voltage self cascode structure. The proposed cell has nearly four times higher output impedance than its conventional version. Dynamic body bias technique increases the intrinsic gain of the proposed cell by 11.17 dB. Analytical formulation for output impedance and intrinsic gain parameters of the proposed cell has been derived using small signal analysis. The proposed cell can operate at low power supply voltage of 1 V and consumes merely 43.1 nW. PSpice simulation results using 180 nm CMOS technology from Taiwan Semiconductor Manufacturing Company (TSMC) are included to prove the unique results. The proposed cell could constitute an efficient analog Very Large Scale Integration (VLSI) cell library in the design of high gain analog integrated circuits and is particularly interesting for biomedical and instrumentation applications requiring low-voltage low-power operation capability where the processing signal frequency is very low.

In this paper, we present a novel operational transconductance amplifier (OTA) topology based on a dual-path body-driven input stage that exploits a body-driven current mirror-active load and targets ultra-low-power (ULP) and ultra-low-voltage (ULV) applications, such as IoT or biomedical devices. The proposed OTA exhibits only one high-impedance node, and can therefore be compensated at the output stage, thus not requiring Miller compensation. The input stage ensures rail-to-rail input common-mode range, whereas the gate-driven output stage ensures both a high open-loop gain and an enhanced slew rate. The proposed amplifier was designed in an STMicroelectronics 130 nm CMOS process with a nominal supply voltage of only 0.3 V, and it achieved very good values for both the small-signal and large-signal Figures of Merit. Extensive PVT (process, supply voltage, and temperature) and mismatch simulations are reported to prove the robustness of the proposed amplifier.

AbstractDue to the increased processing data rates, which is required in applications such as fifth-generation (5G) wireless networks, the battery power will discharge rapidly. Hence, there is a need for the design of novel circuit topologies to cater the demand of ultra-low voltage and low power operation. In this paper, a low-noise amplifier (LNA) operating at ultra-low voltage is proposed to address the demands of battery-powered communication devices. The LNA dual shunt peaking and has two modes of operation. In low-power mode (Mode-I), the LNA achieves a high gain ($$S21$$ S 21 ) of 18.87 dB, minimum noise figure ($${NF}_{min.}$$ NF m i n . ) of 2.5 dB in the − 3 dB frequency range of 2.3–2.9 GHz, and third-order intercept point (IIP3) of − 7.9dBm when operating at 0.6 V supply. In high-power mode (Mode-II), the achieved gain, NF, and IIP3 are 21.36 dB, 2.3 dB, and 13.78dBm respectively when operating at 1 V supply. The proposed LNA is implemented in UMC 180 nm CMOS process technology with a core area of $$0.40{\mathrm{ mm}}^{2}$$ 0.40 mm 2 and the post-layout validation is performed using Cadence SpectreRF circuit simulator.

A low power readout integrated circuit (ROIC) for 512 × 512 cooled infrared focal plane array (IRFPA) is presented. A capacitive trans-impedance amplifier (CTIA) with high gain cascode amplifier and inherent correlated double sampling (CDS) configuration is employed to achieve a high performance readout interface for the IRFPA with a pixel size of 30 × 30 μm2. By optimizing column readout timing and using two operating modes in column amplifiers, the power consumption is significantly reduced. The readout chip is implemented in a standard 0.35 μm 2P4M CMOS technology. The measurement results show the proposed ROIC achieves a readout rate of 10 MHz with 70 mW power consumption under 3.3 V supply voltage from 77 K to 150 K operating temperature. And it occupies a chip area of 18.4 × 17.5 mm2.

Lna Design

This paper presents and discusses a Low-Band (LB) Low Noise Amplifier (LNA) design for a diversity receive module where the application is for multi-mode cellular handsets. The LB LNA covers the frequency range between 617 MHz to 960 MHz in 5 different frequency bands and a 5 Pole Single Throw (5PST) switch selects the different frequency bands where two of them are for the main and three for the auxiliary bands. The presented structure covers the gain modes from −12 to 18 dB with 6 dB gain steps where each gain mode has a different current consumption. In order to achieve the Noise Figure (NF) specifications in high gain modes, we have adopted a cascode Common-Source (CS) with inductive source degeneration structure for this design. To achieve the S11 parameters and current consumption specifications, the core and cascode transistors for high gain modes (18 dB, 12 dB, and 6 dB) and low gain modes (0 dB, −6 dB, and −12 dB) have been separated. Nevertheless, to keep the area low and keep the phase discontinuity within ±10∘, we have shared the degeneration and load inductors between two cores. To compensate the performance for Process, Voltage, and Temperature (PVT) variations, the structure applies a Low Drop-Out (LDO) regulator and a corner case voltage compensator. The design has been proceeded in a 65-nm RSB process design kit and the supply voltage is 1 V. For 18 dB and −12 dB gain modes as two examples, the NF, current consumption, and Input Third Order Intercept Point (IIP3) values are 1.2 dB and 16 dB, 10.8 mA and 1.2 mA, and −6 dBm and 8 dBm, respectively.

Noise Amplifier

An optimized high gain low power low noise amplifier (LNA) is presented using 90 nm CMOS process at 2.4 GHz frequency for Zigbee applications. For achieving desired design specifications, the LNA is optimized by particle swarm optimization (PSO). The PSO is successfully implemented for optimizing noise figure (NF) when satisfying all the design specifications such as gain, power dissipation, linearity and stability. PSO algorithm is developed in MATLAB to optimize the LNA parameters. The LNA with optimized parameters is simulated using Advanced Design System (ADS) Simulator. The LNA with optimized parameters produces 21.470 dB of voltage gain, 1.031 dB of noise figure at 1.02 mW power consumption with 1.2 V supply voltage. The comparison of designed LNA with and without PSO proves that the optimization improves the LNA results while satisfying all the design constraints.
