Abstract
An oscillator device comprises an oscillation circuit configured to generate and provide an oscillating signal. A first biasing circuit is configured to derive a bias current signal in accordance with a control signal and apply the bias current signal to the oscillation circuit to control the amplitude level of the oscillating signal. A reference generating circuit is configured to generate a reference voltage signal and comprises a second biasing circuit configured to derive a reference bias current signal in accordance with the control signal. A comparison circuit is configured to determine an error signal by comparing a voltage signal at an output of the first biasing circuit with the reference voltage signal observed at an output of the second biasing circuit. A controller is configured to determine the control signal related to the error signal and provide the control signal to the first biasing circuit and the second biasing circuit.
