Design of novel QCTGAL circuit

By analyzing the switch-signal theory and the principle of adiabatic circuits, a design scheme of Quaternary Clocked Transmission Gate Adiabatic Logic (QCTGAL) circuit is proposed in this paper. First the scheme by using switch-signal theory and switch-control technology of multithreshold MOS derive the switch level structure of Quaternary Adiabatic Literal Operation (QALO) circuits and Quaternary Adiabatic Signal Generation (QASG) circuits, and the evaluation and energy recovery for circuits can be realized by bootstrapped NMOS transistors and CMOS-latch structure. Then QASG circuits controlled by QALO circuits to realize in or out of quaternary logic signals, and quaternary Min/Max circuits are come true by using this design scheme. PSPICE simulation results verified the valid functionality and the remarkable low-power of the designed circuits.
