Abstract
A monostable multivibrator with current-controllable pulse width and height is presented. The circuit utilizes three operational transconductance amplifiers (OTAs) as switching elements. Two of them compose a Schmitt trigger and the other forms an integrator. The theory of operation is presented and experimental results are used to verify theoretical predictions. A prototype circuit built with commercially available components exhibits less than 4.4% nonlinearity in its current-to-pulse width transfer characteristic from 200 to 1600 /spl mu/s and 20 ppm//spl deg/C temperature coefficient of width over 0/spl deg/C to 75/spl deg/C. The circuit also displays good linearity of current-to-pulse height and 1200 ppm//spl deg/C temperature coefficient of height.
