Abstract :
This paper presents a wide operation frequency range frequency clock generator that is composed of the phase interpolator. The test chip was fabricated in a 0.18μm CMOS process with a 1.8 V supply voltage. The simulation phase noise and power dissipation are -87.28 dBc/Hz at 1 MHz offset frequency from 88.8 MHz and 1.32 mW, -77.47 dBc/Hz and 2.06 mW from 797.8 MHz, respectively. The duty cycle error rate of the output clock frequency is less than 1.5%.
