Patent ID: 10411648

Abstract:
The present invention concerns an electronic oscillator comprising: an LC resonant circuit comprising an inductive component and a capacitive component, the LC resonant circuit being connected to a first reference voltage node and to an oscillator output node; a first transistor connected to the oscillator output node and arranged to periodically operate in a conducting state and a non-conducting state; and a phase shift circuit. A phase shift circuit output is connected to the first transistor, while a phase shift circuit input is connected by a first feedback circuit to the oscillator output node. The phase shift circuit comprises a signal phase shifter for shifting the phase of a first feedback signal from the first feedback circuit by substantially 180 degrees. The phase shift circuit further comprises a signal adder for adding a first signal from the signal phase shifter and a second signal to obtain a summed signal; and a second transistor connected to the signal adder for mirroring the summed signal to the oscillator output node through the first transistor.
