ABSTRACT:
An oscillator (1) includes first frequency-determining elements (13-16) for providing a first oscillation frequency, at least second frequency-determining elements (23, 24) connectable to the first frequency-determining elements (13-16) via at least a switching diode (25, 26) for adjusting the oscillator (1) to a second oscillation frequency, the oscillator further having a supply circuit (27-44, 54) which includes at least a controllable current source (27-30), the supply circuit being coupled to the switching diode (25, 26) for optionally switching the switching diode between a conducting state and a blocked state, and having a current source (4) feeding the oscillator (1). In this oscillator, an improved operating behavior is achieved in that the current source (4) feeding the oscillator (1) is switchable by the supply circuit (27-44, 54), jointly with the connection of the controllable current source (27-30) to a supply current which is dimensioned with respect to a current available from the controllable current source (27-30) in such a way that influences exercised on the operating point and the oscillation amplitude of the oscillator (1) are at least substantially compensated by the connection of at least one of the second frequency-determining elements.
