Abstract
A fractional-N PLL includes a reference oscillator, a multi-modulus divider-based phase-error-to-digital converter driven by the reference oscillator, a digital loop filter, and a digitally controlled oscillator. Digital-to-time to converter mismatch noise cancellation digital logic is between the phase-error-to-digital converter and the digital loop filter. Error from digital-to-time converter component mismatches is partially cancelled by the digital logic.
