Abstract

Representative implementations of devices and techniques provide gain calibration for analog to digital conversion of time-discrete analog inputs. An adjustable capacitance arrangement is used to reduce or eliminate gain error caused by capacitor mismatch within the ADC. For example, the capacitance arrangement may include an array of multiple switched capacitances arranged to track gain error during search algorithm operation.
