Abstract
A rectangular pulse generator circuit with
fast rising and falling edge will be presented in this pa-
per. The generator circuit was designed by controlling the
quantity of carriers in the middle layer from regulating
forward current of the SRD (Step recovery diode), and
then indirectly controlling the pulse width. It is based on
the principle that large reverse current will °ow through
the diode and last for a relatively long time when it is re-
verse biased. Experimental results have been analyzed in
physical level. They are tallied with theoretical results.
The circuit can generate rectangular pulses with rise time
about 150ps, fall time about 250ps, amplitude about 10V
and pulse width adjustable from 1ns to 10ns in 50 load.
The trig jitter is less than 5ps and the amplitude jitter is
better than 4%.
