Abstract :
A simple circuit that can generate current pulses with amplitudes ranging from 100 mA to 5 A and with pulse widths varying from 2 ns to 10 ns, is constructed. It is noted that this current pulser is ideal for driving low impedance loads under 10 Ω and uses only low-voltage power supplies. Current pulses are formed using a shunt-series type step recovery (charge storage) diode circuit in conjunction with several power MOSFETs. A unique biasing scheme has been used to store charge on the step recovery diodes, which eliminates the DC bias current normally used in this configuration
