PULSE SHAPING CIRCUIT WITH MULTIPLIER APPLICATION

摘要

A pulse shaping circuit comprising a series resonant circuit and a shunt resistor-diode damping circuit in combination with a square wave input and a grounded base transistor load to provide a pulse of controlled width and amplitude. The damping circuit dissipates all but the first half cycle of resonant circuit ringing. A dual circuit employs a parallel resonant circuit and common emitter load transistor. In a frequency multiplier application, the resonant circuit is tuned to the desired harmonic frequency and a bandpass filter is connected at the transistor output.
