ABSTRACT:
An oscillator includes at least one oscillator transistor having collector, emitter and base leads, a controllable current source connected between the emitter lead of the at least one oscillator transistor and a supply potential, and a frequency-determining element, such as an oscillating circuit, connected at least to the base or collector lead of the at least one oscillator transistor. A method for controlling the amplitude of the output signal of the oscillator includes supplying a direct voltage variation at the emitter lead of the at least one oscillator transistor resulting from a change in amplitude of a signal applied to the base lead of the at least one oscillator transistor as a controlled variable for the current of the controllable current source. The oscillator may also include a control amplifier. The emitter lead of the at least one oscillator transistor is connected to one input of the control amplifier and the other input of the control amplifier is connected to a reference potential. The reference potential is in a fixed relationship with a direct signal component of a signal present at the base lead of the at least one oscillator transistor. The current of the controllable current source is adjusted as a function of an output variable at the control amplifier.
