Summary :

A CMOS programmable gain amplifier (PGA) with a swiched capacitor offset compensation circuit is described. The mean compensation error is 130µV at the input, and the standard deviation of the compensation error is 50µV. This PGA is applicable to a baseband amplifier for digital radio communication terminals.
