摘要：An oscillator device comprises an oscillation circuit configured to generate andprovide an oscillating signal. A first biasing circuit is configured to derive a bias currentsignal in accordance with a control signal and apply the bias current signal to theoscillation circuit to control the amplitude level of the oscillating signal. A reference

generating circuit is configured to generate a reference voltage signal and comprises asecond biasing circuit configured to derive a reference bias current signal in accordancewith the control signal. A comparison circuit is configured to determine an error signal bycomparing a voltage signal at an output of the first biasing circuit with the referencevoltage signal observed at an output of the second biasing circuit. A controller isconfigured to determine the control signal related to the error signal and provide thecontrol signal to the first biasing circuit and the second biasing circuit.
