| Abstract: | Based on the working characteristic of Schmitt circuits which have two detection thresholds to input signals, this paper proposes that Schmitt circuits have the same sequential characteristic as flip flops which are used as memory units. With the design procedure of sequential circuits, varieties of designs of the traditional CMOS Schmitt circuits are systematically investigated, and some new designs are found. PSPICE simulations prove that the circuits designed in this paper have ideal characteristic of Schmitt circuits. |
