Abstract
A method and apparatus for reducing offset errors in a variable gain circuit is offered. A first programmable gain amplifier is located in a feedforward signal path and a second programmable amplifier is connected in feedback with the first programmable gain amplifier. Each programmable gain amplifier has a separate gain control circuit so that the gain of each programmable gain amplifier can be independently controlled.
