Research paper thumbnail of A wide-band CMOS injection-locked frequency divider

Analog Integrated Circuits and Signal Processing, 2004

Fabricated in a digital 0.18 μm CMOS process the divider can operate up to 15 GHz. The measured locking ranges of the divider for division ratios 4 and 6 are 1.6 GHz and 1.1 GHz wide respectively. The current consumption of the divider is 3.8 mA operating at 1.8 V supply. The active area of the chip is 100×67 μm2.
