ABSTRACT:
A method and apparatus are provided to generate calibration signals to multiple stages in a receiver channel. The multiple stages are calibrated using multiple calibration circuits, where a controller controls each calibration circuit. The controller is coupled to the output of the final stage in the receiver channel through a single comparison unit. The output from the single comparison unit is used by the controller to calibrate each of the multiple stages.
