SU502483A1 - Multivibrator - Google Patents

Description

negative signal. The capacitor 8 begins to discharge through diode 16, the open transistor 2 and the resistor 5. This process lasts until the base-emitter voltage of the closed transistor 1 reaches the opening voltage. Further, an avalanche-like process of overturning the multivibrator into the initial state occurs, when transistors 1, 10 are open and transistors 2, 9 are closed.

The timing of the drive capacitors 7, 2 is charged when the transistors 9, 10 are respectively open, i.e., the latter also serve as disconnecting elements of the collectors of the transistors 1, 2 (main), which allows reducing the charge time constant of the drive capacitors and thus improve the leading edge of the pulses.

Subject invention

A multivibrator on transistors with collector-base capacitive connections, containing emitter repeaters in charge circuits, with their capacitors and separation diodes connected between the collectors of the main transistors and the time of the transmitter, with their capacitors, load resistors, characterized in that , in order to form in a load of opposite-polarity pulses, the junction point is the time of the driving capacitor and the separation diode of each arm of the multivibrator through the corresponding, successively connected additional condensers and load resistor connected to the emitters of the main transistors.
