Abstract

The invention relates to an electronic driver circuit (EDC) for driving a resonator element (XO) for providing an electronic oscillator (1). The electronic driver circuit (EDC) comprises: a synthesizer section (SYN) which is configured to receive a reference signal (XO_SIG.N, XO_SIG.P) from the resonator element (XO) and to generate a synthesizer signal (SYN_SIG) having a synthesizer frequency (SYN_F) which is equal to, lower or higher than a reference frequency (XO_F) of the reference signal (XO_SIG.N, XO_SIG.P), and having in particular a phase resolution below or equal to 90 degrees with respect to the reference signal (XO_SIG.N, XO_SIG.P); and a pulse injection section (PJD.N, PJD.P) which is configured to inject an injection signal (INJ.N, INJ.P) into the resonator element (XO) at an injection time (T.N, T.P) which is selected using the synthesizer signal (SYN_SIG), or using the synthesizer signal (SYN_SIG) and the reference signal (XO_SIG.N, XO_SIG.P). The electronic driver circuit (EDC) enables providing an electronic oscillator (1) having improved power and noise efficiency.
