Abstract
An analogue to digital converter includes a first input connection to receive a first part of the analogue input signal, a second input connection to receive a second part of the analogue input signal, a first and second plurality of capacitors, each capacitor of the first plurality of capacitors forms a capacitor pair with a corresponding capacitor in the second plurality of capacitors During a sampling period, the first input connection couples the first part of the analogue input signal to a first contact of each capacitor of the first plurality of capacitors and the second input connection couples the second part of the analogue input signal to a first contact of each capacitor of the second plurality of capacitors. Further, a switching array couples a second contact of each capacitor of the first and second plurality of capacitors to a common mode voltage to determine a first bit of a digital output signal.
