Abstract
Improvements in an oscillator circuit characterized in that it comprises a first and a second amplifying element, for example, transistors, each of which has a first, a second and a third electrode, which can be base, emitter and collector respectively, the second electrodes of said first and second element being coupled to each other through a series resonant circuit, said first amplifying element, which works in its active region, having its first polarized electrode with a normally constant DC voltage and its third electrode coupled to its first electrode of said second amplifier element whose amplitude limited the oscillator feedback signal. Characterized in that it also comprises a third amplifying element (Q3), for example, a transistor, which has at least a first, a second and a third electrode, which can respectively be base, emitter and collector, the first and second electrodes being of said third element, which works in its active region, coupled to the third electrode of said first element (Q1) and to the first electrode of said second element (Q2) and because the resistance of the resonant return circuit is small with respect to the inductance thereof, whereby the signals at the third electrodes of said first and third elements are sinusoidal.
