초록

A current-controlled OTA-R schemitt trigger circuit is described. It consists of two OTA's and two resistors. The output level of the circuit is determined by one OTA and one resistor, and the threshold level by the other OtA and resistor. The theory of operation is presented and computer simulation results and experimental results using CMOS arrays are used to verify theoretical predictions. The results show close agreement between predicted behaviour and experimental performance.
