Abstract
An oscillator formed of an amplifier with a feedback loop containing two parallel connected crystals in series with a voltage variable capacitance. The two crystals have respective resonance frequencies above and below the limits of a wide band over which the oscillator frequency can be varied by a control voltage. Frequency versus control voltage linearity is improved by inductances inserted in parallel and in series, respectively, with the lower and higher frequency crystals.
