Title:
【発明の名称】高周波電圧制御型発振器の非線形性の検出および補正方法
Document Type and Number:
Japanese Patent JP2002539650
Kind Code:
A
Abstract:
A method for detecting and correcting non-linearities in radio-frequency, voltage controlled oscillators provides for digitization of the frequency signal by feeding the undelayed frequency signal and a delayed frequency signal generated therefrom into EXOR gates. The digital pulses produced thereform are converted using a low pass filter into a proportional DC voltage value which is proportional to the oscillator frequency and is used as a basis for producing a correction value for the frequency control of the oscillator.
