Abstract
A first gain stage and a second gain stage having different gains are linked in cascade to construct a wide range and high resolution programmable gain amplifier. The second gain stage can be used only for low gain and low power consumption. Furthermore, two pairs of chopper circuits are used to shift flicker noise when the programmable gain amplifier is operated.
