Patent ID: 7898350

Claim:
A frequency stabilizing device of an oscillator for stabilizing the frequency of an oscillator to keep the frequency in constant when an input voltage is changed, wherein the frequency stabilizing device of oscillator comprises: a plurality of gate elements comprising a plurality of metal-oxide-semiconductors (MOS); a plurality of voltage sources coupled to the plurality of gate elements as the input voltage of the plurality of gate elements; and a plurality of resistors coupled to the plurality of gate elements; wherein the gate elements coupled to the voltage source generate a current which flows though the gate elements and is proportional to the input voltage, the gate elements comprise a first transmission gate and a second transmission gate, and the resistors are two resistors, one terminal of a first resistor is directly connected to one terminal of a second resistor at a node which is coupled to an output terminal of the oscillator, the other terminal of the first resistor is coupled to a first terminal of the first transmission gate, and the other terminal of the second resistor is coupled to a first terminal of the second transmission gate.
