Abstract

Resonant circuit arrangement including at least two transistors with emitters, bases and collectors, the collector of the first transistor being connected to the base of the second transistor and the collector of the second transistor being connected to the base of the first transistor by means of displacement elements of phase connected to the transistors in order to obtain a positive feedback dependent on the frequency produced by the resonant character, characterized in that the collector circuit of each transistor includes a rectifier polarized in the direction of passage and on which a voltage is produced which compensates the voltage drop on the emitter-base path of the respective transistor.
