Design of 2-4 mixed-valued/eight-valued up-down counter on switch-level(2-4混值/8值绝热加减法计数器开关级设计)
通过对8值逻辑编码技术、绝热电路和加减法计数器工作原理及结构的研究,提出带进位/借位的2-4混值/8值绝热加减法计数器设计方案.首先,该方案以开关信号理论为指导,分别推导出2-4混值/8值触发型绝热正循环门和进位/借位电路的开关级结构式,然后利用多阈值NMOS管和交叉存贮结构实现相应电路,并在此基础上实现带进位/借位的2-4混值/8值加减法计数器.最后,PSPICE模拟验证所设计的电路具有正确的逻辑功能,在55.6 MHz工作频率下,与常规CMOS 2-4混值/8值加减法计数器相比,节省功耗约95%....
