  • Abstract
    This paper proposes a CMOS low noise variable gain amplifier (VGA). It describes the noise optimization method of the proposed VGA. The designed VGA provides of a 0 to 21.30 dB gain variation and with bandwidth of 49 MHz. The input reflected noise voltage is 4.84 nV/sqrt-Hz at 1 MHz and noise figure is 14.53 dB(Rs=50 Ω). The VGA was fabricated using 0.35-μm CMOS technology
