The high speed reaction differential pulse generating circuit

Published:2011/6/23 21:01:00 Author:Seven | Keyword: high speed reaction, differential pulse | From:SeekIC

In the circuit, the transistor VT1 and VT2 compose the difference amplifier circuit, to raise the reaction speed, the circuit works in non-saturation state. If the input pulse is 0～＋5V, the collecting electrode current is higher than TV2 when it is 0V, if the input is +5v, then the collecting electrode current of VT2 is rising quickly, and the differential waveform is got by L1. VD1 is the Schottky diode of high speed switch, which only allows the forward waveform to conduct VT3. Its basic pole current flows in VT3, then there is collecting electrode current, the LEV is falling quickly and generates a passive differential pulse.
