A circuit for calibrating a coarse channel circuit in a folding analog-to-digital converter circuit. A reference value is input to the coarse channel circuit and an output of the coarse channel circuit is sensed. A parameter of the coarse channel circuit is adjusted until the coarse channel circuit is successfully calibrated.
