This paper describes a new low-voltage low-power TSPC complementary pass-transistor logic circuit for 1.2V applications. The proposed logic circuits are implemented with only NMOS differential pass- transistor logic network and controlled by true-single-phase clock signal to form the pipelined structures. Due to the limited voltage swing and current-sensing scheme, the proposed TSPC logic circuits have certain advantages in both operation speed and power dissipation. Moreover, it can be designed and fabricated without changing the conventional 5V, 0.6μm CMOS process. Based upon the HSPICE simulation results the differential-input TSPC structure reach a 185MHz operation frequency in a adder circuit for 1.2V supply voltage.
