Abstract
An oscillator circuit () comprising a resonator () connected serially with a series to series feedback amplifier (), in which the series to series amplifier comprises a feedback network () which has an impedance value which is below a certain first predefined limit and a phase value which increases with the operational frequency of the oscillator circuit with a rate which is above a second predefined limit. In one embodiment, the impedance value of the feedback network () also varies with the operational frequency of the oscillator circuit, but is always below said first predefined value within the operational frequency of the oscillator circuit.
