This paper presents the design and implementation of a low-noise amplifier (LNA) for millimeter-wave (mm-Wave) 5G wireless applications. The LNA was based on a common-emitter configuration with cascode amplifier topology using an IHP’s 0.13 μm Silicon Germanium (SiGe) heterojunction bipolar transistor (HBT) whose f_T/f_MAX/gate-delay is 360/450 GHz/2.0 ps, utilizing transmission lines for simultaneous noise and input matching. A noise figure of 3.02–3.4 dB was obtained for the entire wide bandwidth from 20 to 44 GHz. The designed LNA exhibited a gain (S_21) greater than 20 dB across the 20–44 GHz frequency range and dissipated 9.6 mW power from a 1.2 V supply. The input reflection coefficient (S_11) and output reflection coefficient (S_22) were below −10 dB, and reverse isolation (S_12) was below −55 dB for the 20–44 GHz frequency band. The input 1 dB (P1dB) compression point of −18 dBm at 34.5 GHz was obtained. The proposed LNA occupies only a 0.715 mm2 area, with input and output RF (Radio Frequency) bond pads. To the authors’ knowledge, this work evidences the lowest noise figure, lowest power consumption with reasonable highest gain, and highest bandwidth attained so far at this frequency band in any silicon-based technology.

A 3.1 ~ 10.6 GHz Ultra-Wideband SiGe Low Noise Amplifier (LNA) is proposed. This low noise amplifier utilizes a current-reused technique to increase the gain and extend the bandwidth. We have a detailed analysis for the input matching, noise figure, gain and other features. The LNA was designed with the TSMC 0.35µm bipolar silicon-germanium (SiGe) processes. Simulation results show that the input reflection coefficient is less than-9dB, the output reflection coefficient is less than-10dB, the maximum power gain of 17 dB and the minimum noise factor (NF) of 2.35dB. The total power consumption is 6.2 mW with 2.5V power supply.

AbstractA 3–12 GHz ultra-wideband (UWB) low noise amplifier (LNA) is proposed in this paper. The first stage common-gate (CG), common-source (CS) noise canceling approach is used to achieve low noise-figure (NF). CG configuration at the input stage provides wideband input-matching. The noise of CG transistor is cancelled by systematically added two parallel CS transistors, whose outputs are cascoded in second stage. In order to achieve flat power gain (S21) response, a series peaking inductor is used in the second stage. The proposed LNA is designed in 90 nm CMOS process with chip-layout area of 0.467 mm2 and in comparison to the existing LNAs, it consumes a low power of 5.7 mW from a 1 V supply. The achieved input-reflection coefficient (S11) is <−7.5 dB, output-reflection coefficient (S22) is <−7.6 dB with NF < 5.8 dB for 3–12 GHz UWB and third-order intercept point (IIP3) of −19 dBm. It achieves high and flat S21 of 20.84 ± 0.28 dB over 4.2–10 GHz, with NF ranging from 2.6–3.6 dB.

This paper features the design approach of a low noise amplifier (LNA) which dissipates 19.89 mW from a 1.2 V power supply that was designed based on a 0.13 μm RFCMOS process. A detailed methodology that leads to a power-efficient design of the LNA is presented. A theoretical noise figure optimization using fixed power and physics-based gm/ID characteristics were used as a design optimization guide. Simultaneous noise and input matching under constrained power (PCSNIM) was achieved with an extra gate-source capacitor while gain enhancement was obtained by employing a capacitive feedback at the cascode transistor.  The LNA is further optimized by implementing the forward biasing scheme to attain good LNA performance at low power. The end-design of the optimized LNA produces a noise figure of 3.55 dB, a power gain of 17.12 dB, a Third Order Input Intercept Point (IIP3) of -19.70 dBm, an input reflection coefficient of -14.15 dB and an output reflection coefficient of -18.37 dB. Simulated results validate peak performance at 2.45GHz, which makes the LNA suitable for Bluetooth and the industrial, scientific and medical (ISM) applications.

A two-path low-noise amplifier (LNA) is designed with TSMC 0.18[Formula: see text][Formula: see text]m standard RF CMOS process for 6–16[Formula: see text]GHz frequency band applications. The principle of a conventional resistive shunt feedback LNA is analyzed to demonstrate the trade-off between the noise figure (NF) and the input matching. To alleviate the mentioned issue for wideband application, this structure with noise canceling technique and linearity improvement are applied to a two-path structure. Flat and high gain is supplied by the primary path; while the input and output impedance matching are provided by the secondary path. The [Formula: see text][Formula: see text]dB bandwidth can be increased to a higher frequency by inductive peaking, which is used at the first stage of the two paths. Besides, by biasing the transistors at the threshold voltage, low power dissipation is achieved. The [Formula: see text][Formula: see text]dB gain bandwidth of the proposed LNA is 10[Formula: see text]GHz, while the maximum power gain of 13.1[Formula: see text]dB is attained. With this structure, minimum NF of 4.6[Formula: see text]dB and noise flatness of 1[Formula: see text]dB in the whole bandwidth can be achieved. The input impedance is matched, and S[Formula: see text] is lower than [Formula: see text]10 dB. With the proposed linearized LNA, the average IIP[Formula: see text][Formula: see text]dBm is gained, while it occupies 1051.7[Formula: see text][Formula: see text]m die area.

A wideband (2–3 GHz) three-stage low noise amplifier (LNA) with electrostatic discharge (ESD) protection circuits using 0.18 [Formula: see text]m CMOS technology is presented in this paper. Low-parasitic silicon-controlled rectifier (SCR) devices are co-designed with the LNA in the form of [Formula: see text]-parameters, and a new cascaded L-match input network is proposed to reduce the parasitic effects of them on the input matching. To improve linearity performance, an optimized multiple-gated transistors method (MGTR) is proposed and applied to the third stage, which takes both transconductance [Formula: see text] and third-order nonlinear coefficient [Formula: see text] into consideration. The measured results show a wide input matching across 2–8 GHz and a high third-order input intercept point (IIP3) of −12.8 dBm. The peak power gain can achieve 29.1 dB, and the noise figure (NF) is in a range of 3.1–3.6 dB within the 3-dB bandwidth. Using SCR devices with low parasitic capacitance of [Formula: see text]80 fF and robust gate-driven power clamps, a 6.5-kV human body mode (HBM) ESD performance is obtained.

This chapter aims to discuss a millimeter wave integrated circuit (MMWIC) in frequency of 30 GHz especially switch (SPDT), medium power amplifier (MPA) and low noise amplifier (LNA). The switch is developed using a commercial 0.15 µm GaAs pHEMT technology. It achieves low loss and high isolation for millimeter wave applications. The circuit and layout drawing of SPDT switch are done by using Advanced Design System (ADS) software. The layout is verified by running the Design Rules Check (DRC) to check and clear all the errors. At the operating frequency of 30 GHz, the reported SPDT switch has 1.470 dB insertion loss and 37.455 dB of isolation. It also demonstrates 26.00 dBm of input P1dB gain compression point (P1dB) and 22.975 dBm of output P1dB. At a supply voltage of 3.0 V and 30 GHz operating frequency, this two-stage LNA achieves an associated gain of 21.628 dB, noise figure (NF) of 2.509 dB and output referred 1-dB compression point (P1dB) of -11.0 dBm, the total power consumptions for the LNA is 174 mW. At a supply voltage of 6.0 V and 30 GHz operating frequency, a 2-stage MPA achieves a linear gain (S21) of 13.236 dB, P1dB of 22.5 dBm, power gain of 11.055 dB and the PAE of 14.606%.
