Abstract:
A repeater circuit. The repeater circuit includes two output circuits, two echo 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, which is configured to drive an output signal on an output node. A corresponding echo circuit is configured to be activated and to drive an input node responsive to activation of the corresponding output circuit. A corresponding one of the deactivation circuits is configured to deactivate the corresponding output circuit after a delay time has elapsed, whereas the corresponding echo 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 circuit.
