Patent ID: 6960939

Claim:
A dynamic logic circuit having an output and a complementary output comprising: a first electronic switch having an input terminal coupled to a clock signal, a first terminal coupled to a positive power supply voltage and a second terminal coupled to a dynamic node of said dynamic logic circuit, wherein said dynamic node is coupled to said positive power supply voltage in response to a first logic state of a clock signal and isolated from said positive power supply voltage in response to a second logic state of said clock signal; a logic tree having a plurality of logic inputs, a positive tree terminal coupled to said dynamic node and a negative tree terminal, wherein said positive tree terminal is coupled to said negative tree terminal in response to a first combination of logic states of said plurality of logic inputs and isolated from said negative tree terminal in response to a second combination of logic states of said plurality of logic inputs; a second electronic switch having an input coupled to said clock signal, a first terminal coupled to said negative tree terminal and second terminal coupled to a negative power supply voltage, wherein said negative tree terminal is coupled to said negative power supply voltage in response to said second logic state of a clock signal and isolated from said positive power supply voltage in response to a first logic state of said clock signal; a keeper circuit having a power supply terminal coupled to a positive power supply voltage, a keeper output coupled to said dynamic node, a keeper input coupled to said complementary output, wherein said keeper circuit reinforces a second logic state on said dynamic node only when said dynamic node evaluates to the logic one state and said output is the logic one state before transitioning to the logic zero state; and static output logic circuitry having an input coupled to said dynamic node, a static output generating said output, an inverted static output generating said complementary output, and an enable terminal, wherein said enable terminal is coupled to said negative power supply voltage by a third electronic switch in response to said second logic state of said clock signal and by a fourth electronic switch in response to said second logic state of said complementary output.
