Implemented using a standard 40 nm RF CMOS process, the proposed LNA demonstrates more than 12dB gain and less than 5.1 dB noise figure across the 24 GHz to 27 GHz band, with input and output return loss below - 15 dB.

LNA circuits in CMOS technology are designed as Common Source (CS) or Common Gate (CG) stages. Cascode stage that is widely used in CMOS RF LNAs, can be considered as current –reuse configuration of a CS stage, followed by a CG stage.

An Ultra WideBand CMOS Low Noise Amplifier (LNA) is presented. Due to really low power consumption and extremely high data rates the UWB standard is bound to be popular in the consumer market. The LNA is the outer most part of an UWB transceiver. The LNA is responsible for providing enough gain to the signal with the least distortion possible.

Oct 22, 2018 · In CMOS, Cgd can be ≈ 50% of Cgs, and the fT of the cascode stage is at least 33% smaller than that of the transistor. Thus, CMOS cascode LNA stage requires bandwidth extension techniques in order to achieve acceptable gain at mmWave frequencies.

The CS-LNA configuration is currently popular because of its superior noise performance; i.e., the inductive degeneration is ideally noiseless and the RF input signal is pre-amplified by the input-matching series resonant network.

An RF LNA is designed here using CMOS 90nm technology for low power operation with a current reuse technique for biasing. The bias current is shared between the two transistor stages and a method for feeding the signal from the first stage to second stage using parallel resonance for isolation of the drain and source regions of the transistors ...

LNA DESIGN IN CMOS r- formance radio receivers. It is usually the first block of th receiver after the antenna. The LNA amplifies the input signals so that the noise generated by following blocks has little impact on the system signal-to-noise (SNR) ratio. If the gain of LNA is sufficient, the receiver's SNR is
