ABSTRACT:
An oscillation circuit including an amplifier portion wherein the collector of a first switching transistor has a load connected thereto, means is provided for transmitting an output of the collector of the first switching transistor to the base thereof, means is provided for transmitting the output of the collector of the first switching transistor to the base of a second switching transistor, and the collector of the second switching transistor has a load connected thereto. A capacitive element is connected between the collector of the second switching transistor and the base of the first switching transistor of the amplifier portion so as to feedback an output of the second switching transistor to the first switching transistor to operate the circuit as an oscillator.
