1. An oscillator circuit comprising:

  • an input and an output arranged for connection of a resonator therebetween;

    inverter means having a first driver transistor and a second driver transistor coupled in series via said output;

    biasing means having a first biasing element coupled between said output and a control electrode of the first driver transistor for biasing the first driver transistor, and a second biasing element coupled between said output and the control electrode of the second driver transistor for biasing the second driver transistor;

    first limiting means coupled between the control electrode of said first driver transistor and a first node for receiving a signal representative of the signal at the output, and second limiting means coupled between the control electrode of said second driver transistor and a second node for receiving a signal representative of the signal at the output, the control inputs of the first and second driver transistors being capacitively coupled to the input.
