Abstract

An ultra-wideband low noise amplifier(LNA) based on the cascode configuration with resistive feedback is presented in this paper. A shunt-shunt feedback resistor and a pre-π matching network is employed to achieve wideband input impedance matching, and to enhance gain response and reduce noise for using a post-cascode inductor LP. In this paper, the SMIC 40nm CMOS process is used. The circuit simulation results show that S11 is lower than -10dB, and the gain S21 is around 10±2dB,and the NF is lower than 4.5dB in the 3.5-31-GHz frequency range.
