Abstract :
A low power all-digital phase locked-loop (ADPLL) in a 0.13um CMOS process is presented. The pulse-based digitally controlled oscillator (PB-DCO) performs a high resolution and wide range. The locking time of ADPLL is less then 32 reference clock cycles. The multiplication factor is 2 to 63. Power consumption is 260uW at 160-MHz and 80uW at 60-MHz with 0.5V supply voltage.
