A new Schmitt trigger circuit comprises of single multiple output current follower differential input transconductance amplifier and one grounded resistor is presented. The presented circuit provides both clockwise and anticlockwise hysteresis simultaneously with independent and electronic control of threshold levels. The amplitudes of output currents are also independent and electronically controllable. Experimental results using commercial ICs have been depicted to confirm theoretical analyses.
