Draw and explain Schmitt-trigger circuit as a input protection for CMOS. Also explain bi-directional i/o circuits.
written 3.0 years ago by |
Schmitt trigger circuits are often used as input circuits to guard against noise-induced false switching. Schmitt triggers are characterized by having hysteresis in their voltage transfer curve. The hysteresis insures that small fluctuations on the rising or falling edge of the input signal do not induce a false switching event. …
