Trimming of a two point phase modulator

The claimed is used to calibrate method and system for VCO with phase modulator automatic gain. Method and system of this invention uses with a frequency control input and modulate the input and feedback loop controlled oscillator the phase modulator synthesize methods to the output frequency signal. The frequency control signal to the frequency control input, and to control the gain variation of oscillator and compensation of the feedback loop via the modification input. Method and system of this invention can be used to any of the phase and amplitude modulation telecommunications system, comprising EDGE and WCDMA system.
