ABSTRACT:
A method for converting a repeater circuit from a dynamic repeater circuit to a static repeater circuit. The method includes disconnecting a feedback path coupled to a first stage of the dynamic repeater circuit and electrically shorting gate terminals of first and second transistors of a second stage to each other, wherein the transistors of the second stage are configured to drive an output signal on an output node. Disconnecting the feedback path and electrically shorting the gate terminals is performed by reconfiguring a plurality of selection devices in the repeater circuit from a first configuration to a second configuration. The repeater circuit includes at least one keeper configured to provide an output signal on the output node.
