ABSTRACT:
A repeater circuit. The repeater circuit includes a first output stage having two output circuits, a second output stage having two additional output circuits, two activation circuits, and two deactivation circuits. Responsive to detecting a logical transition of an input signal, one of the activation circuits is configured to activate a corresponding output circuit, and responsive thereto another corresponding output circuit is configured to be activated. The output circuits drive an output signal on the output node. A corresponding one of the deactivation circuits is configured to deactivate the corresponding output circuit after a delay time has elapsed, whereas the other corresponding output circuit is deactivated in response thereto. A keeper circuit is configured to continue providing the output signal on the output node after deactivation of the corresponding output circuits.
