which causes the appearance of a positive potential equal to the voltage drop at the forward-displaced pn-junction of the drain of the transistor 10 - the substrate. Then, the charge of the capacitor 14 begins after the time of the transistor 7 and the open transistor 10. The one-shot operation in the second half-period is similar. A change in the potential at the gates of the time of the setting transistors 7 and 9 using the control voltage supplied to the bus 16 makes it possible to vary the frequency of the generated pulses. Claims of the invention One-vibration on field-effect transistors according to the author. St. 513576, characterized in that, in order to provide a self-oscillating mode of operation, a two-input OR-NOT circuit and a field-effect transistor are additionally introduced into it, the inputs of the OR-NOT circuit are connected to the trigger outputs, the output of the OR circuit is NOT connected to the gate of the field-effect transistor, the drain which is connected to the capacitor time of the master circuit, and the source - to the common bus.  t  LL Lji; a and 1: b4  ,,   г4-, -Jj-rl - / --- М z i 4G-P / L, zf
