Abstract
A current-controllable Schmitt trigger using operational transconductance amplifiers (OTAs) is presented. It consists of two OTAs and two grounded resistors. The output level of the circuit is determined by one OTA and one resistor. And the threshold level is determined by the other OTA and resistor. The theory of operation is presented and experimental results are used to verify theoretical predictions
