ABSTRACT:
A pulse shaper circuit includes a buffer having an input, an output and two supply connections. A controllable first switch is connected between one of the supply connections and a first supply potential, a controllable second switch is connected between the other supply voltage connection and a second supply potential, a controllable third switch is connected between the output of the buffer and the first supply potential and a controllable fourth switch is connected between the output of the buffer and the second supply potential. A control device for the switches is connected to the output of the buffer and produces a first control pulse of a specific duration at the occurrence of first edges of a signal present at the output of the buffer and a second control pulse of a specific duration at the occurrence of second edges. The first control pulse changes over the first switch from the ON state to the OFF state and the fourth switch from the OFF state to the ON state. The second control pulse changes over the second switch from the ON state to the OFF state and the third switch from the OFF state to the ON state.
