Abstract

PURPOSE:To secure the steady working of the pulse duration expanding device, by clamping the terminal voltage of the capacitor to the prescribed level at the starting point of dischrarge and then setting the minimum input pulse duration necessary for generation of the output signal. CONSTITUTION:With application of the clamping input signal to terminal 10, transistor 11 is turned on. And the terminal volatage of capacitor 5 is clamped to the voltage of power source 9. Thus terminal volatage V0 of capacitor 5 can be kept constant at the starting point of discharge by carrying out said operation immediately before application of the input signal to terminal 1. On the other hand, the minimum input pulse duration (t) which is necessary for generation of the output signal to terminal 7 is set by the time constant during the discharge determined by value R3 of resistance 3 and capacity value C5 of capacitor 5 puls trigger voltage Vt of Schmitt trigger circuit 9 and voltage V0. Accordingly, duration (t) can be set to a fixed value as long as voltage V0 is constant. As a result, a pulse duration expanding device having an extremely steady working can be obtained.
