Study on ternary clocked transmission gate adiabatic logic circuit

通过分析开关—信号理论和绝热电路工作原理及结构,提出三值钟控传输门绝热逻辑(Ternary Clocked Transmission Gate Adiabatic Logic,TCTGAL)电路设计方案。该方案利用NMOS管自举效应和CMOS-latch结构对输出负载进行充放电,并通过NMOS管栅漏并接对输出降压限幅;然后依据开关—信号理论推导出三值绝热文字运算电路的开关级结构式,并在此基础上实现T运算电路。最后,PSPICE模拟验证所设计的电路具有正确的逻辑功能和显著的低功耗特性。

By analyzing the switch-signal theory,the working principle and structure of Clocked Transmission Gate Adiabatic Logic（CTGAL） circuit is presented and a design scheme of Ternary Clocked Transmission Gate Adiabatic Logic（TCTGAL） circuit is proposed in this paper.The scheme makes output loads be charged or discharged in adiabatic manner by bootstrapped NMOS and CMOS-latch structure,and the output voltage amplitude will be limited by joining-up grid and drain in parallel of NMOS;then according to switch-signal theory the switching-level structure of ternary adiabatic literal circuits is derived and the T-operation is come true by using this design scheme.PSPICE simulation results verify the valid functionality and the remarkable low-power of the designed circuits.
