Abstract
In an embodiment, a frequency synthesizer includes a digitally controlled oscillator configured to generate an output clock signal based on a digital control word, a clock divider configured to divide the output clock signal to generate a divided clock signal, a digital-to-time converter configured to generate a feedback clock signal based on the divided clock signal, a time-to-digital converter configured to generate a phase error signal based on a bias control word and a phase difference between a reference clock signal and the feedback clock signal, a loop filter connected to the time-to-digital converter and configured to generate the digital control word based on the phase error signal, and a calibration unit configured to generate a training sequence to generate a gain error signal, and modify the bias control word based on the gain error signal to generate a modified bias control word.
