Abstract: The disclosed embodiments provide a resonant oscillator circuit. The resonant oscillator circuit includes a clipping mechanism configured to clip an output voltage of a signal pulse generated by the resonant oscillator circuit to a predefined constant level. The resonant oscillator circuit also includes a feedback path configured to return energy from the clipping mechanism to an input of the resonant oscillator circuit.
