Wideband Inductorless Low-Noise Amplifier Using Three Feedback Paths

Mahsa Emami Tabar, Jafar Sobhi, Ziaeddin Daie KuzeKanani


This paper presents the design of a wideband inductorless low noise amplifier (LNA) in 0.18 m CMOS technology for multiband wireless communication standards. The LNA is a fully differential common-gate structure. It uses three feedback paths, for choosing arbitrary value of LNA transconductance which leads to a LNA with higher gain and lower noise figure (NF) over the previously reported amplifiers. Post-layout simulation results show a gain of 20.4 dB with a 3-dB bandwidth of 2.84GHZ, with a 2.62dB NF while dissipating 2.97mW. The IIP3 is -1.67dBm
