Abstract
A technique for resetting state variables of a delta-sigma modulator of an analog-to-digital converter. A switched capacitor impedance is placed in the reset feedback path of an integrator to ensure that the integrator tracks to the proper reset voltage, when reset is initiated in a third-order or higher delta-sigma modulator.
