Abstract
An arrangement and a method for connecting a capacitor into a circuit and disconnecting it therefrom are disclosed. The capacitor includes two capacitor elements, each with a main terminal and an auxiliary terminal. The auxiliary terminals are connected to one another at a reference node to which a control signal can be coupled as a function of the desired capacitance value. The capacitance value is tapped at the main terminals of the capacitor elements. When the capacitor is switched on, a high quality level is obtained, and when the capacitor is switched off, low parasitic capacitance components are obtained. For this reason the described arrangement is particularly suitable for use in voltage-controlled oscillators.
