Jz. Shen et Pd. Tougaw, DESIGN OF SYMMETRICAL TERNARY CURRENT-MODE CMOS SCHMITT INVERTER, International journal of electronics, 85(4), 1998, pp. 477-482
We propose the design of a symmetric ternary current-mode CMOS Schmitt
inverter using transmission current-switch theory. This Schmitt inver
ter can have multiple outputs, and its width of hysteresis can be adju
sted as needed. The computer simulation shows that the designed Schmit
t inverter has nearly ideal Schmitt characteristics.
