Abstract : The patent describes a voltage-tunable oscillator continuously variable over seven decades having a positive feedback circuit connected between a digital-logic gate and a first, field-effect transistor, the drain-to-source impedance of which is selectively varied by means of a potential applied to the gate thereof from an externally controlled source for establishing a desired frequency of operation. A second, field-effect transistor is connected as a source follower between said first, field-effect transistor and said digital-logic gate. The oscillator output inputs a buffer circuit having an external oscillation inhibit capability.
