A highly linear, digitally programmable gain amplifier (PGA) based on an inherently linear MOS current divider (MCD) is presented in this paper. A 3-bit prototype with a total variation range of 36dB ...

A design for an instrumentation amplifier with digitally programmable gain and common-mode rejection (CMR) trim is presented. A standard multiplying D/A converter (DAC) is used as the differential ...
