Patent ID: 8406077

Claim:
An apparatus comprising: a first dynamic circuit structure comprising a first keeper circuit, a first discharge circuit, and a first precharge circuit, wherein the first keeper circuit, the first discharge circuit, and the first precharge circuit are coupled to a first dynamic node and wherein the first precharge circuit is configured to precharge the first dynamic node to a precharge voltage level; and a second dynamic circuit structure comprising a second keeper circuit, a second discharge circuit, and a second precharge circuit, wherein the second keeper circuit, the second discharge circuit, and the second precharge circuit are coupled to a second dynamic node and wherein the second keeper circuit is further coupled to the first dynamic node, wherein the first dynamic circuit structure receives an asserted discharge signal during a discharge time period, the asserted discharge signal at a discharge voltage level different than the precharge voltage level, and wherein a single one of the first dynamic circuit structure and the second dynamic circuit structure that receives the asserted discharge signal operates as a level shifter to generate an output signal to a second voltage domain in response to receiving the asserted discharge signal from a first voltage domain.
