This paper presents the design of a CMOS low-noise amplifier (LNA) with partial inductive degeneration using active inductors in [Formula: see text]m technology. Both, the inductor of the partial degeneration and the load inductor, are actives. The inductors configurations are cascode with feedback resistance and Wu folded compact. The LNA has a gain of 13.2[Formula: see text]dB and a noise figure of 4.7[Formula: see text]dB at 1.8[Formula: see text]GHz. The layout has an active area of [Formula: see text]. The results are satisfactory, validating the compact design and demonstrating the technical feasibility of this proposed topology.

In this paper, focuses on the design of Low Noise Amplifier circuitry in the frequency band L. This circuit is designed using the 0.18 nm CMOS transistor technology, which consists of two transistor Stage. The purpose of this research is to improve the cost of: Increase Gain - Increase circuit linearization - Create an integrative matching network for system stability. The application of this circuit can be used in wireless and GPS systems. The CMOS LNA exhibits a gain greater than 23 dB from 1.1 to 2.0 GHz, and a noise figure of 2.7 to 3.3 dB from 1.2 to 2.4 GHz. At 1.575 GHz, the 1-dB compression point (P1dB) is 1.73 dBm, with an input third-order intercept point (IIP3) of -3.98 dBm. This circuit is designed using ADS software.

This paper presents a wideband low noise amplifier (LNA) for multi-standard radio applications. The low noise characteristic and input matching are simultaneously achieved by active-feedback technique. Bond-wire inductors and electrostatic devices (ESDs) are co-designed to improve the chip performance. Implemented in 0.18-μm CMOS process, the core size of the fully integrated LNA circuits is 535 μm×425 μm without any passive on-chip inductor. The simulated gain and the minimal noise figure of the CMOS LNA are 17.5 dB and 2.0 dB, respectively. The LNA achieves a -3dB bandwidth of 3.1 GHz. And the simulated IIP3 is -4.4 dBm at 2.5 GHz. Operating at 1.8V, the LNA draws a current of 7.7 mA.

A fully integrated CMOS tunable image-rejection low-noise amplifier (IRLNA) has been designed using Silterra's industry standard 0.18 μm RF CMOS process. The notch filter is designed using an active inductor. Measurement results show that the notch filter designed using active inductor contributes additional 1.19 dB to the noise figure of the low-noise amplifier (LNA). A better result is possible if the active inductor is optimized. Since active inductors require less die area, the die area occupied by the IRLNA is not significantly different from a conventional LNA, which was designed for comparison. The proposed IRLNA exhibits S21 of 11.8 dB, S11 of −17.8 dB, S22 of −10.7 dB, and input 1 dB compression point of −12 dBm at 3 GHz

The aim of this paper is to design and implement a low noise amplifier (LNA) based on transformer for a Ku-band application. The proposed CMOS LNA can have an enhanced gain because of the cascade topology, a highly flat gain response because of the RC feedback network, and a wide passband because of the source degeneration structure that effectively suppresses the Miller effect. The Ku-band LNA dissipates 22.175 mW power and achieves the S11 of -10.31 to -6.77 dB, S22 of -18.1 to -37.78 dB, flat S21 of 8.78 to 10.59 dB, and noise figure of 3.96 to 5.33 dB across the 12~18 GHz span. The measured output P1dB is approximately -2 dBm. The chip size including all testing pads is only 0.545 x 0.599 mm2.
