ABSTRACT:
There is provided a pulse generating circuit, which generates two pulses having a sign of amplitude different from each other, including: a step recovery diode of which electric potential of an anode and a cathode is respectively output as the pulses; a bias unit operable to select either a forward bias or a backward bias according to a given control signal and apply the selected bias to the step recovery diode; a forward current source operable to prescribe a forward current to be supplied to the step recovery diode when the forward bias is applied to the step recovery diode; and a backward current source operable to prescribe a backward current to be supplied to the step recovery diode when the backward bias is applied to the step recovery diode.
