Abstract:
1. A push-pull circuit receiving an input signal and providing an output signal, the push-pull circuit comprising: a pull-up device; a pull-down device; a switched capacitor circuit coupled to the pull-up device and the pull-down device; and at least one feedback path coupling the output signal to the switched capacitor circuit, wherein the feedback path enables dynamic control of the pull-up device and the pull-down device, wherein the at least one feedback path comprises a first and second feedback path, and wherein the switched capacitor circuit during a first phase is configured to provide the first feedback path coupling the output signal to the pull-up device and not the pull-down device, and the second feedback path coupling the output signal to the pull-down device and not the pull-up device; and wherein during a second phase the first feedback path and the second feedback path are open.
