Abstract
The present document relates to oscillator circuits and a method. An oscillator circuit generates an oscillating voltage signal, wherein the crystal has a first electrode and a second electrode. The oscillator circuit has a power source with a supply terminal and a reference terminal. The oscillator circuit has a switching circuit arranged between the power source and the crystal. The switching circuit, in a start-up phase, alternately connects the supply terminal of the power source to the first and second electrode of the crystal such that an amplitude of the oscillating voltage signal is increased.
