Abstract
A charge compensation circuit for use in an analog-to-digital converter (ADC) includes at least one capacitor and at least one logic circuit. A first terminal of the capacitor is coupled to a reference voltage of the analog-to-digital converter. The logic circuit is configured to adjust a voltage at a second terminal of the capacitor according to a control signal. The control signal is determined according to at least one output bit from the analog-to-digital converter.
