Abstract:
A latch circuit includes a feed-forward circuit, a keeper circuit, and a feed-back circuit. The feed-forward circuit includes a first-inverting-stage with a first input and a first output, wherein the first-inverting-stage comprises a first clocked device, and a second-inverting-stage with a second input and a second output, wherein the second-inverting-stage comprises a second clocked device, and a keeper circuit. The first output is operatively connected to the second input. The keeper circuit is operatively connected to the first output, and the keeper circuit is driven from the second output. The feed-back circuit includes a third-inverting-stage with a third input and a third output, wherein the third input is operatively connected to the second output, and a fourth-inverting-stage with a fourth input and a fourth output. The fourth input is operatively connected to the third output. The fourth output is connected to the third input to form a storage node.
