摘要： A circuit arrangement for generating oscillations with a defined frequency includes an oscillator circuit (30, 32) for generating the oscillations and a dedamping circuit (18, 20) connected to the oscillator circuit for compensating any damping of the oscillator circuit. The dedamping or damping compensation by the dedamping circuit is accomplished with the aid of a rectifier circuit (60, 62). The dedamping circuit is a bridge circuit of CMOS field effect transistors (22, 24; 26, 28) which are controlled in their operation in closed loop fashion by respective rectifier circuit branches which are in turn connected to the oscillator circuit to provide a proportional closed loop control of the damping compensation.
