Abstract
An oscillator utilizing a pair of transistors interconnected with a resonance circuit in the collector circuits thereof such that by regulation of the current flow to the connected emitters, the frequency of oscillation is regulated.
Claims2
A transistor oscillator comprising, in combination:
- first and second transistors;
- a current source connected to supply current to each transistor emitter;
- a first circuit including a short circuit conductor connected between the base of said first transistor and the collector of said second transistor;
- a second circuit including a short circuit conductor connected between the base of said second transistor and the collector of said first transistor;
- a resonance circuit connecting said first and second circuits;
- a current return path from one said circuit to the current supply whereby oscillatory signals will be generated in the circuits;
- means to regulate the current flow from the source through the transistors to provide current at levels exceeding the saturation of the transistors to vary the frequency range of the oscillator signals;
- and
- means to detect the frequency of oscillation across the resonance circuit.
