摘要：

A variable gain amplifier (VGA) is described with a 35-dB range and 50-MHz bandwidth in 2-mu-m CMOS. The circuit occupies 0.8-mm2 active area, dissipates 150 mW, and embodies a semilogarithmic 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.
