| 摘 要： | 利用电流信号的阈值易于控制这一特点,对电流型CMOS电路中如何实现阈值控制进行了研究.以开关信号理论为指导,建立了实现阈值控制电路的电流传输开关运算并具体指导设计了具有阈值控制功能的二值和多值电流型CMOS全加器.提出了适用于任意逻辑值的可控阈电流型CMOS全加器的通用设计方法.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,在性能上也获得了改善.最后给出了采用0.25μm CMOS工艺参数的HSPICE模拟结果及其能耗比较.

| Abstract: | Since current threshold values are easy to control,this paper studies how to realize the threshold controlling in current-mode CMOS circuits.Guided by the switch signal-theory,the operations of current transmission switch used to realize threshold-controlling circuits are established.On this basis,binary and multiple-valued current-mode CMOS adders with threshold-controllable function are designed.A universal design method for current-mode CMOS m-valued adders based on threshold-controllable technique is proposed.By employing the threshold-controlling technique,the construction of the circuits has been simplified considerably,and the performance of the circuits has been improved.HSPICE simulations of transient characteristics using 0.25μm CMOS technology are presented,and the simulated results of energy dissipation are compared. |
