A 2.4 GHz very low-power programmable fractional frequency divider is presented in this work. A new kind of pulse swallowing architecture is exposed, offering news possibilities in terms of frequency range, frequency step and power consumption. This circuit was designed and implemented in 28nm FDSOI CMOS from STMicroelectronics. The divider consumes 300 μA over 1 V.
