ABSTRACT:
A circuit for charging or discharging a capacitive load. The circuit includes a buffer driver comprising first and second input terminals and an output terminal, and a reference voltage generator coupled to the buffer driver. The reference voltage generator includes an enablement signal terminal, first and second reference voltage terminals, and a circuit operable to provide first and second reference voltages at the first and second reference voltage terminals in response to a first signal at the enablement terminal. The reference voltage generator also provides first and second rail voltages in response to a second signal at the enablement terminal.
