Abstract:
A True Single Phase Clock (TSPC) latch design with symmetrical input data paths. A first input data path includes: a first NMOS transistor coupling a gate of a first PMOS transistor to VSS in response to a rising input data signal, and a second PMOS transistor having a gate coupled to a logic low (VSS) input clock signal, whereby the first and second PMOS transistors turn on to couple a data input node to VDD. A second input data path includes: a third PMOS transistor having a gate coupled to a falling input data signal (VSS), a fourth PMOS transistor having a gate coupled to a logic low (VSS) input clock signal, whereby the third and fourth PMOS transistors turn on to couple a gate of a second NMOS transistor to VDD, whereby the second NMOS transistor turns on to couple the data input node to VSS.
