A 120dB all CMOS variable gain amplifier based on new exponential equation

This paper presents the design of a two-stage wide dynamic range variable gain amplifier (VGA). This is based on a new approximated exponential equation which offers a wide decibel linear range and an improved fully differential MOS Cherry-Hooper topology. In addition, the bandwidth of the VGA has b...
