Abstract: A fractional frequency divider configured to suppress spurious tones resulting from requantization of an accumulated quantization error has a multi-modulus divider (MMD) and one or more digital-to-time converters (DTCs). Each DTC includes a gain and/or digital predistortion, a dithered requantizer having a multibit input signa, a multibit output signal, and a multibit digitally-controllable delay (DCD).
