Abstract
A CMOS wave shaping buffer circuit comprises two CMOS inverter stages connected as a non-inverting buffer. In addition, the two stages are further coupled by way of their supply connections to produce a positive feedback from the second stage to the first whenever both stages are driven to a linear state, that is both transistors of each stage are “ON”. The positive feedback prevents the output stage from remaining in a logically ambiguous state, but forces crisp transitions from one state to another even for slowly changing input signals.
