ABSTRACT:
A switched capacitor circuit having an integrator, a switch, a capacitor, a field effect transistor, and a network. The switch is connected to the integrator. The capacitor is connected to the switch. The field effect transistor is connected to the capacitor. The network is connected to a gate terminal of the field effect transistor. The network is configured to control a resistance of the field effect transistor in response to variations in an input signal voltage received at the field effect transistor.
