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.

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.

In this paper, a 60 GHz complementary metal-oxide-semiconductor (CMOS) balun low-noise amplifier (LNA) was implemented for millimeter-wave communication. To improve the gain and noise performance, slow-wave coplanar waveguides (S-CPW) with high quality factor were designed as input, output, and inter-stage matching networks. At the input port, a balun transformer provides additional passive gain while performing the singled-ended to differential conversion. Implemented in a 28-nm CMOS process, simulated results show that the proposed LNA exhibits a simulated linear gain of 16 dB and a noise figure of 5.6 dB at 60 GHz, with a 3-dB gain bandwidth of 5 GHz (58 GHz–63 GHz). The input return loss is better than −25 dB at the central frequency. The simulated input third-order intercept point (IIP3) is −5 dBm. The circuit draws 35 mA from 1 V supply voltage.

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.
