A 26[Formula: see text]GHz low-noise amplifier (LNA) designed for 5G applications using 0.18[Formula: see text][Formula: see text]m CMOS technology is proposed in this paper. The circuit includes a common-source in the first stage to suppress the noise in the amplifier. The successive stage has a Cascode topology along with an inductive feedback to improve the power gain. The input matching network is designed to achieve the input reflection coefficient less than [Formula: see text]7dB at the intended frequency. The matching network at the output is designed using inductor–capacitor (LC) components connected in parallel to attain the output reflection coefficient of [Formula: see text]10[Formula: see text]dB. Due to the inductor added in feedback at the second stage. The [Formula: see text] obtained is 18.208[Formula: see text]dB at 26[Formula: see text]GHz with a noise figure (NF) of 2.8[Formula: see text]dB. The power supply given to the LNA is 1.8[Formula: see text]V. The simulation and layout of the presented circuit are performed using Cadence Virtuoso software.

The present paper presents a fully differential 60 GHz four stages low-noise amplifier for wireless applications. The amplifier has been optimized for low-noise, high-gain, and low-power consumption, and implemented in a 90 nm low-power CMOS technology. Matching and common-mode rejection networks have been realized using shielded coplanar transmission lines. The amplifier achieves a peak small-signal gain of 21.3 dB and an average noise figure of 5.4 dB along with power consumption of 30 mW and occupying only 0.38 mm2pads included. The detailed design procedure and the achieved measurement results are presented in this work.

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.

This research present a design of a higher  gain (66.38dB) for PHEMT LNA  using an inductive drain feedback technique for wireless application at 5.8GHz. The amplifier it is implemented using PHEMT FHX76LP transistor devices.  The designed circuit is simulated with  Ansoft Designer SV.  The LNA was designed using  T-network as a matching technique was used at the input and output terminal,  inductive generation to the source and an inductive drain feedback. The  low noise amplifier (LNA) using lumped-component provides a noise figure 0.64 dB and a gain (S<sub>21</sub>) of 68.94 dB. The output reflection (S<sub>22</sub>), input reflection (S<sub>11</sub>) and return loss (S<sub>12</sub>) are -17.37 dB, -15.77 dB and -88.39 dB respectively. The measurement shows the  stability was at  4.54 and 3-dB bandwidth of 1.72 GHz. While, the  low noise amplifier (LNA) using  Murata manufactured component provides a noise figure 0.60 dB and a gain (S<sub>21</sub>) of 66.38 dB.
