Abstract
Systems and methods for compensating a non-linearity of a digitally controlled oscillator (DCO) are presented. Data comprising a plurality of silicon measurements is received. Each silicon measurement in the plurality of silicon measurements is compared to an ideal value. Based on the comparing, a plurality of compensation vectors is generated. Each compensation vector comprises at least one silicon measurement. At least one frequency is adjusted based on a compensation vector in the plurality of compensation vectors. A digitally-controlled oscillator frequency is generated based on the adjusted at least one frequency.
