Abstract
The invention is directed to a resonant circuit having a frequency-determining element which has at least one switchable frequency-changing element connected in parallel therewith. The frequency-changing element has two series-connected transistors whose control connections are connected to a node that receives a fixed potential. First connections of the two series-connected transistors are connected to one another and also to a control input for a control signal for switching the frequency-changing element of the resonant circuit. The invention keeps the control voltage for the two transistors at a higher potential than the threshold voltage for the transistors. This reduces a parasitic capacitance in the two transistors during operation.
