Abstract :
A 150-450-MHz, all-digital phase locked-loop (ADPLL) in a 0.18um CMOS process is presented. The pulse-based digitally controlled oscillatr (PB-DCO) performs a high resolution and wide range. The bulk-controlled varactor minimizes jitter performance. The worst case for frequency acquisition is 32 reference clock cycles. The multiplication factor is 2-63. The rms and peak-to-peak jitters are 6.7ps and 44ps at 450-MHz, respectively. Power consumption is 16.2mW at 450-MHz.
