Abstract

A frequency synthesizing module includes an operating circuit, for generating a control voltage according to a reference signal and a feedback signal; a controllable oscillating circuit, configured for generating an oscillating signal according to the control voltage and a first control signal, comprising a first oscillating circuit with a first frequency gain, and a second oscillating circuit with a second frequency gain; a feedback circuit, for generating the feedback signal according to the oscillating signal and a second control signal; a control circuit, for generating the first control signal and the second control signal; wherein the control circuit adjusts the first control signal by a first value and adjusts the second control signal by a second value to estimate the first frequency gain of the first oscillating circuit; wherein the first value is proportional to the second value.
