Abstract
An oscillator is provided having an oscillator circuit including at least one oscillator circuit inductor and a first oscillator circuit capacitor, whereby the value of the first oscillator circuit capacitor is reversible by means of the first control voltages between different stages. The oscillator is characterized by a first control voltage source, which applies first control voltages with at least three stepwise different values to the first oscillator circuit capacitor. Preferably, the control voltages are generated over a network of current sources and resistors, whereby the network compensates for the thermal response of the oscillator. Further, a method for operating this type of oscillator is presented.
