This invention describes a method for gain tuning of a voltage-controlled oscillator of a phase locked loop (PLL) of an electronic device using voltage measurements and a frequency iteration. The invention presents a method of minimizing integrated VCO gain variations. More specifically, the invention implementation is based on an analysis which includes changing the VCO frequency by iteration steps and optionally calculating said iteration steps and measuring a gain of said voltage controlled oscillator (VCO) at said frequencies changed by the iteration steps, wherein the analysis is based on a predetermined criterion. The present invention can be used in any radio architecture that requires limiting of the VCO gain variation and tuning its center frequency.
