Abstract:
1. An apparatus, comprising: a dynamic circuit driven by a one-shot clock signal to operate in either a pre-charge mode or an evaluation mode, the dynamic circuit comprising a dynamic node and a pull down network that implements a set of logic, the pull down network evaluating, when the dynamic circuit is operating in evaluation mode, a set of input to provide a data signal at the dynamic node; and a clock circuit configured to generate the one-shot clock signal that drives the dynamic circuit, wherein the clock circuit receives as input a power-off signal which, when asserted, causes the pull down network to be deactivated, and wherein the clock circuit, in response to the power-off signal being asserted, causes the one-shot clock signal to drive the dynamic circuit into pre-charge mode, thereby causing the dynamic node to be pulled to a pre-charge voltage to ensure that the dynamic node does not float when the pull down network is deactivated.
