  • 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%.
