A circuit for producing an output signal at an output thereof in response to an input signal at an input thereof is comprised, in one embodiment, of a first switch for connecting the output to a first voltage source and a second switch for connecting the output to a second voltage source. A first control switch is provided for turning off the first switch in response to the logic level of the input signal while a second control switch is provided for turning off the second switch in response to the logic level of the input signal. An integrator is responsive to the input signal for turning on one of the first and second switches depending on the logic level of the input signal. A method of operating such a circuit is also disclosed.
