ABSTRACT:
Driver circuits for switched-capacitor circuits are implemented using a variety of methods and devices. According to one such circuit, a switched-capacitor driver circuit is implemented for producing an output signal by driving a capacitive output load in response to step input signals. The driver circuit includes output circuitry that drives the capacitive output load toward a steady-state mode responsive to one of the step input signals and control circuitry that, before realizing the steady-state mode, inhibits the output circuitry from driving the capacitive output load to the steady-state mode.
