Abstract
A CMOS Schmitt Trigger circuit design provides a relatively high speed device having a tight, substantially monotonic hysteresis characteristic which is substantially independent of fabrication process parameters and can be used with relatively wide power supply designs, including operating a relatively low Vcc. Tight trip point variation is maintained in conjunction with process, voltage, and temperature changes. The circuit is adaptable for forming an integrated circuit buffer element.
