Abstract
The response time of an ordinary or differential transistor switching circuit controlled by the charging of a capacitor C.sub.1 is shortened by charging the capacitor through a constant current source comprising a transistor Q.sub.6, a resistor R.sub.1 and diodes D.sub.1, D.sub.2, to thereby provide a sharp transfer characteristic. The charging time may be even further shortened by increasing the constant current supply at an intermediate threshold level using a further ordinary or differential transistor switching circuit, thereby providing a break in the response characteristic and increasing its slope after the threshold point.
