ABSTRACT:
A stepped pulse generator circuit has an input line for receiving a sawtooth form voltage and an output line for providing a step-shaped pulse. First and second differential amplifiers each have first and second transistors the first transistor of each differential amplifier has its base electrode coupled to the input line. A common load resistor for the differential amplifiers is coupled to the collector electrode of the first transistor of the first differential amplifier, to the collector electrode of the second transistor of the secon differential amplifier and to the output line. A biasing circuit is coupled with the base electrode of the second transistor of the first differential amplifier and with the base electrode of the second transistor of the second differential amplifier and is arranged to provide a different bias potential on each base electrode. Current supply is provided to the emitter electrodes of the transistors of the first and second differential amplifiers.
