Gain-Error Calibration of a Pipelined ADC in an Adaptively Equalized Baseband Receiver

Two approaches to calibrate a pipelined analog-to-digital converter (ADC) and adapt an equalizer in a baseband receiver are proposed. Adaptive digital correction is used to calibrate the weights applied to the ADC output decisions so that the mean square error across the slicer in the receiver is minimized. Simulation results are presented to demonstrate the joint calibration of a pipelined ADC and adaptation of a channel equalizer.
