US 2010/0164556 A1 · CONVERTING DYNAMIC REPEATERS TO CONVENTIONAL REPEATERS

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.

An electronic circuit comprising:

a first stage coupled to an input node;
a second stage coupled to the first stage and an output node;
a feedback path coupled between the second stage and the first stage;
a keeper coupled between the input node and the output node;
and
a plurality of switches, wherein when the plurality of switches are in a first configuration, the electronic circuit is configured to act as a dynamic repeater circuit, wherein the second stage is configured to be activated responsive to a logic transition of an input signal and is further configured, when activated, to drive an output signal responsive to a logical transition on the input node, and wherein the first stage is configured to, after a delay time, deactivate the second stage responsive to a receiving a feedback signal via the feedback path, and wherein the keeper circuit is configured to provide the output signal on the output node subsequent to deactivation of the second stage;
and
wherein, when the plurality of switches are in a second configuration, the electronic circuit is configured to act as a static repeater circuit, wherein the feedback path is disabled and wherein the keeper circuit is configured to provide the output signal on the output node.
