Abstract

This paper presents an ultra-low-voltage and low-power all-digital (AD) PLL. The AD-PLL consists of time-to-digital converter (TDC) combined 8-phase digitally controlled ring oscillator. The proposed AD-PLL eliminates a delay-line based TDC and suited for ultra-low-voltage and low-power operation in wide frequency range. The AD-PLL designed and fabricated in 40nm-CMOS technology operates with power consumption of 45.5μ\ν at 0.5V power supply and 100MHz output frequency. The AD-PLL has power scalability from 10MHz to 100MHz with normalized power consumption lower than 0.47μW/μηz. The core area is 0.037mm².
