This paper presents a new dynamic frequency divider which generates a 1/4N frequency component, i.e. 1/4, 1/8, 1/12, . The frequency divider consists of a multi-stage transfer-gate-inverter pair and an additional inverter. The additional inverter enables the operation of frequency dividers with even-stage buffers, and results in frequency division by 4N. Delaycontrol circuits are also employed to widen the operation range of the frequency divider. A Prototype of 30 GHz-band 1/8 frequency divider was fabricated using 0.1 µm InP HEMT device. The measured operation range was 2.5 GHz in 30 GHz band, and power consumption was only 60 mW.
