摘　　要：首先对二值ＣＭＯＳ施密特电路的设计思想进行了分析，指出设计施密特电路的关键为阈值控制电路。根据三值ＣＭＯＳ电路有两个信号检测阈的特点，提出了通过文字电路将两个检测阈分离后进行分别控制并由文字电路的输出去控制ＣＭＯＳ传输门的设计方法，由此设计了三值ＣＭＯＳ施密特反相器。By analyzing the design idea of binary CMOS Schmitt circuits firstly, this paper indicates that the key of the design of Schmitt circuits is threshold controlling circuits. Based on the characteristic of having two kinds of signal detection threshold in ternary CMOS circuits, this paper proposes a design method that the two detection thresholds are controlled respectively after they are separated by literal circuits and then the CMOS transmission gate is controlled by the output of literal circuits. Thereby, a ternary CMOS Schmitt inverter is designed. The simulation with PSPICE proved that the designed circuit has ideal function of Schmitt circuits.
