A high speed frequency divider in 0.18μm CMOS for wireless sensor networks

This paper presents a 1V low-voltage high speed frequency divider-by-2 which is fabricated in a standard 0.18μm TSMC RF CMOS process. Employing parallel current switching topology, the 2:1 frequency divider operates up to 6.5GHz while consuming 4.64mA current with test buffers at a supply voltage of 1V, and the chip area of the core circuit is 0.065×0.055mm
