Abstract
Integrated pulse former constructed in MIS circuit technology and connected to a first supply potential as well as to a second supply potential serving as a reference potential, and acted upon by control pulses from a pulse generator, which includes a first former part and a second former part directly addressed by the control pulses from the pulse generator, the first former part being connected to both the first and the second supply potentials and having three signal outputs, the second former part being additionally controlled via the three signal outputs of the first former part and being connected only to the first one of the two supply potentials, a first one of the signal outputs connected to and controlling a gate of a first field-effect transistor having a source-chain path directly connected, on one hand, to an output of the pulse generator furnishing the control pulses and, on the other hand, to a signal output of the second former part for furnishing secondary pulses, a second one of the three signal outputs of the first former part being connected to and controlling a gate of a second field-effect transistor having a source-drain path connecting the signal output of the second former part to one terminal of a capacitor having another terminal connected to the third one of the three signal outputs of the first former part, the one terminal of the capacitor connected to the second field-effect transistor being also connected via a third field-effect transistor to the first supply potential, the third field-effect transistor having a gate controllable, respectively, by the first supply potential and by pre-charging pulses applied to the first former part for controlling the first former part; and means provided for effecting a return of the first, second and third potentials at the respective signal outputs of the first former part to a state prevailing before onset of a final control pulse, after the end of the falling edge of the control pulses from the pulse generator and before onset of the rising edge of the next control pulse.
