Abstract

The disclosure relates to a receiver system that employs multiple instances of a DC compensation system to reduce DC offsets in a receiver path. The receiver has a receiver front end configured to receive an RF input signal and to operate on the RF input signal according to a plurality of receiver states to generate a baseband signal having a DC offset that is based upon the plurality of receiver states. A DC offset compensation circuit implements a plurality of instances of DC offset compensation components that respectively generate an estimated DC offset corresponding to a receiver state. A controller controls the receiver state of the receiver front end and operates the DC offset elimination circuit to selectively apply one of the plurality of DC compensation components to the corresponding baseband signal based upon the receiver state.
