Abstract

A driver device for a voltage-controlled oscillator, having an unstable voltage source, a voltage regulator, a driver for generating a control voltage for the oscillator, and a feedback loop which controls the driver as a function of the output signal of the oscillator; the voltage regulator supplying the feedback loop with operating voltage while the driver is powered by the unregulated voltage of the voltage source, and the feedback loop compensates for voltage fluctuations of the voltage source with the aid of the driver.
