Abstract :
A new high-speed dynamic CMOS frequency divider that operates at frequencies of over 16 GHz is proposed. The core of the proposed 2:1 divider consists of only three inverters and one transmission gate, and it has no DC current. Using the 2:1 divider, we developed a 64:1 divider with 0.2-μm CMOS/SIMOX technology. Experimental results show that the maximum input frequency of the proposed divider is 1.4 times as high as that of a conventional one. The proposed 64:1 divider has a high input frequency of 16.3 GHz with a power consumption of 45 mW at 2.0-V power supply, and a low power consumption of 2.0 mW with a input frequency of 7.0 GHz at 0.8-V power supply
