Abstract
An ultra low voltage energized oscillator for providing a stepped-up alternating current voltage is provided. This oscillator utilizes a field effect transistor with a high impedance network including a capacitor coupling a feedback signal from a secondary output winding to a primary input winding of a transformer.
Claims5
A low voltage driven oscillator circuit, including:
- transformer means having a first winding and a second winding with said windings magnetically coupled;
- solid state current control means having current conducting path means and further including current control electrode means;
- said current conducting path means and said first winding connected in a series circuit and said series circuit adapted to be connected to a source of low voltage, direct current potential;
- high impedance circuit means including connection means connecting said current control electrode to a first end of said second winding and to a first output conductor for said oscillator circuit;
- and common connection means connecting a second output conductor for said oscillator circuit to a second end of said second winding which in turn is connected to said solid state current control means.
