Optimization of noise figure and gain of a CMOS RF low noise amplifier

Abstract

In this paper forward body bias technique is implemented on a low noise amplifier to improve its noise figure and gain. The forward body bias is applied in the conventional Low-Noise Amplifier design which accounts for the low Noise-Figure and high Gain in it. The cascode LNA operating at 24 GHz without forward body bias is compared with the LNA having forward body bias using the PTM 65-nm technology. The simulation results show that the bias applied reduces the noise figure and increases the gain of the proposed circuit.
