Abstract

This paper proposes a CMOS low noise VGA. It describes the noise optimization method of the proposed VGA. The designed VGA provides of a 0 to 21.30dB gain variation and its bandwidth of 49MHz. The input reflected noise voltage is 4.84nV/sqrt-hz at 1MHz and noise figure is 14.53dB(Rs=50 Ω). The VGA was fabricated using a 0.35-${\mu}{\textrm}{m}$ CMOS technology.
