Abstract
A dual FET oscillator includes a first J-FET and a second J-FET connected to it as a source follower. A turned circuit is connected to the gate of the first J-FET and to the second J-FET. Bias voltage is supplied to both J-FET's. Schottky diodes are connected to both J-FET's to limit gate-source voltage.
Claims4
