Low-Power TSPC 2/3 Frequency Prescaler in Low-Cost 180nm CMOS

This paper presents a 2/3 frequency prescaler designed in low-cost 180nm CMOS process. The prescaler features low direct-current (DC) power consumption, by combing true single-phase clock with embedded NOR gates. The measured results validated that, whit a low DC power consumption of 0.77/1.08 mW only, the 2/3 frequency prescaler has a maximum operation frequency of 2.68 GHz and 2.38 GHz, under divide-by-2/3 modes respectively.
