Abstract
Systems, apparatuses, and methods for implementing low voltage clock swing sequential circuits are described. An input signal is coupled to the gates of a first P-type transistor and a first N-type transistor of a first transistor stack. A low voltage swing clock signal is coupled to the gate of a second N-type transistor of the first transistor stack. An inverse of the input signal is coupled to the gates of a second P-type transistor and a third N-type transistor of a second transistor stack. The low-swing clock is coupled to the gate of a fourth N-type transistor of the second transistor stack. A first end of one or more enabling P-Type transistors with gates coupled to the low-swing clock is coupled to the first P-type transistor's drain, and a second end of the one or more enabling P-Type transistors is coupled to the second P-type transistor's drain.
