Balanced Transistor Multivibrator

This free running multivibrator having a balanced and consistent operation is relatively insensitive to transistor types and characteristics.

Two transistors 10 and 11 of opposite conductivity types are coupled in complementary fashion. A balanced feedback is provided by couplings, including capacitors 12 and 13, between the collector of each transistor and the base of the other. Both transistors are maintained floating, or free of direct current bias, except that which is provided through the associated elements.

Synchronizing signals are applied to the circuit at terminals 14 to provide a triggered operation. The multivibrator action is achieved by having both transistors alternately conducting and cut off, so that low duty cycles are achieved.
