| 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 sequen-tial characteristic as flip-flops which are used as memory units. With the design procedure of sequential circuits, varieties of Schmitt circuits based on integrated gate circuits are systemati-cally investigated, and some new designs are found. PSPICE simulations prove that the circuits designed in this paper have ideal characteristic of Schmitt circuits. |
