Abstract:
Inventive aspects include a dynamic flip flop, comprising a data independent P-stack feedback circuit. The data independent P-stack feedback circuit may include a first P-type transistor gated by a first dynamic inverted net signal, and a second P-type transistor gated by an inverted clock signal. A drain of the second P-type transistor may be coupled to a source of the first P-type transistor. A source of the second P-type transistor may be coupled to a node that is configured to receive a second dynamic inverted net signal. The source of the second P-type transistor may be directly coupled to the node that is configured to receive the second dynamic inverted net signal instead of a constant power source. The data independent P-stack feedback circuit may include one or more delay stages to eliminate race conditions.
