Abstract
A simplified current-tuned bipolar junction transistor oscillator is provided that is especially adapted for low power applications. The oscillator hereof utilizes the diffusion capacitance of the transistor's forward-biased base-emitter junction together with an inductance connected directly across the transistor's base-collector junction as reactive elements in the oscillator's frequency determining network. The transistor's base-collector junction is operated at zero volts bias thereby insuring that its depletion capacitance is fixed. The input current to the emitter is varied to change the base-emitter diffusion capacitance thereby adjusting the oscillator's frequency of oscillation.
