Abstract
A method is provided for operating a voltage controlled oscillator, particularly in a portable communications appliance, when the oscillator is supplied with a variable control voltage, which is taken from an operating voltage, preferably from a constant voltage source, such that the variable control voltage is supplied via a capacitor to the oscillator, and the specific additional voltage is added to the variable control voltage when required in an operating phase, with the specific additional voltage being inclined to the capacitor in a preparation phase.
