Abstract
A controllable LC oscillator has a constant inductance and a constant capacitance. In an oscillator circuit comprising a parallel resonant circuit, voltage limiting components are connected in parallel with the resonant circuit. By way of a controllable impressed current source, the starting point of voltage limitation is controlled and, hence, an alteration of the oscillator frequency is effected. In addition, a dual of the oscillator circuit is provided comprising a series resonant circuit.
