Short Description

Tough frequency synthesize requirement imposed by cellular applications have been a key driver for PLL research in recent years. As the age of cellular internet of things is coming, motivation for designing power efficient PLL (supreme phase noise performance at low power) is getting stronger than ever. Locating at the heart of PLL, VCO does not only determine the phase noise performance of PLL (especially far out part) but also contributes considerably to the total power budget. As the result, stringent design specifications provide considerable incentive for research solely focused on improving the voltage-controlled oscillator (VCO) performance, one of the most challenging aspects of PLL design. The aim of this project is to analyze and build such a power efficient sub-10 mW Digital controlled Oscillator (DCO) for GHz frequency range, to achieve a state-of-art performance, finally leading the way to a low power low jitter Digital PLL.
