Claims
- 1. An edge-triggered latch comprising:a pair of complementary data inputs; at least one pass-transistor logic (PTL) transmission gate configured as a pass-gate with respect to each of said pair of complementary data inputs and having a pair of gate terminals connected to a first and second control node, wherein said at least one PTL transmission gate passes data from said pair of complementary data inputs into a pair of complementary storage nodes in response to a differential latch trigger pulse applied to said first and second control nodes; and a differential pulse generator including a first and a second latch trigger PTL transistor that pass said differential latch trigger pulse to said first and second control nodes in response to a clock signal transition.
- 2. The edge-triggered latch of claim 1, wherein said at least one PTL transmission gate comprises an N-type field-effect transistor and a P-type field-effect transistor, and wherein the gate of said N-type field-effect transistor is coupled to said first control node and the gate of said P-type field effect transistor is coupled to said second control node.
- 3. The edge-triggered latch of claim 2, wherein said differential latch trigger pulse comprises a positive level pulse and a negative level pulse, and wherein said differential pulse generator comprises:a positive pulse generator for generating said positive level pulse; and a negative pulse generator for generating said negative level pulse.
- 4. The edge-triggered latch of claim 3, wherein said positive pulse generator is coupled to said first control node and said negative pulse generator is coupled to said second control node.
