Abstract:
The disclosure provides a circuit that includes an integrator that generates an integrated signal in response to a current signal. A comparator is coupled to the integrator and receives the integrated signal and a primary reference voltage signal. The comparator generates a feedback signal. A switched capacitor network is coupled across the integrator. The feedback signal activates the switched capacitor network.
