Abstract
A current-steering offset compensation circuit is configured for compensating an offset caused by process variation or environment variation of a signal processor. The signal processor includes a pair of differential input terminals and a pair of differential output terminals. The current-steering offset compensation circuit comprises a current-steering circuit connected with the signal processor, a digital control unit which generates a digital control signal according to the outputs from the pair of differential output terminals of the signal processor, and a digital-to-analog converter which receives the digital control signal and outputs a control voltage, wherein the current-steering circuit receives the control voltage, so as to steer the current of the pair of differential input terminals, to reduce the offset in the signal processor.
