Abstract
An oscillator arrangement is described including a resonant circuit having two poles from which an oscillation generated in the oscillator arrangement can be taken and including a differential amplifier of two emitter-coupled transistors having two collector electrodes of which each one is connected to one of the poles of the resonant circuit, and having two base electrodes cross-coupled to the poles of the resonant circuit. Such an oscillator arrangement can be constructed so as to generate a low-noise oscillation by means of a minimal number of circuit elements in that the base electrodes are each coupled to the poles of the resonant circuit via a diode configuration.
