摘要 以开关信号理论为指导,对电流型CMOS电路中如何实现阈值控制进行了讨论.建立了实现阈值控制电路的电流传输开关运算.在此基础上设计了具有阈值控制功能的电流型CMOS三值全加器.通过对开关单元实施阈值控制后,所设计的电路在结构上得到了非常明显的简化,在性能上也获得了优化.HSPICE模拟验证了所提出的电路具有正确的逻辑功能,并且较之以往设计具有更好的瞬态特性和更低的功耗. Guided by the switch signal-theory, this paper discussed how to realize the threshold controlling in current-mode CMOS circuits. The operations of current transmission switch used to realize threshold-controlling circuits were established. On this basis, an improved current-mode CMOS ternary adder with threshold-controllable function was designed. By employing the threshold-controlling technique, not only the construction of the circuit was simplified considerably but also the performance of the circuit was improved. The computer simulations with HSPICE demonstrated that the proposed adder has correct logic function, better transient characteristics and lower power dissipation than those of the previously reported one.
