Abstract:
A pulse shaper circuit, comprising:a buffer having an input, an output and two supply connections;a controllable first switch connected between one of said supply connections and a first supply potential;a controllable second switch connected between the other of said supply connections and a second supply potential;a controllable third switch connected between said output of said buffer and the first supply potential;a controllable fourth switch connected between said output of said buffer and the second supply potential; andcontrol circuitry connected to said output of said buffer for controlling said switches,said control circuitry producing a first control pulse of a specific duration at an occurrence of first edges of a signal present at said output of said buffer, said first control pulse changing over said first switch from an ON state to an OFF state and changing over said fourth switch from an OFF state to an ON state, andsaid control circuitry producing second control pulse of a specific duration at an occurrence of second edges of the signal present at said output of said buffer, said second control pulse changing over said second switch from an ON state to an OFF state and changing over said third switch over from an OFF state to an ON state.
