  • Abstract
    A variable-gain amplifier (VGA) with a 35-dB range and 50-MHz bandwidth in 2-μm CMOS is described. The circuit occupies 0.8-mm2 active area, dissipates 150 mW, and embodies a semilogarthic relation between gain and control voltage. Although developed for use in magnetic storage read channels, this general-purpose block may be used in a variety of applications
