An Ultra-Low-Power ADPLL for BLE Applications

In recent years, wireless personal area network (WPAN) applications have triggered the needs for low-cost and low-power PLLs which also provide good performance. All-digital phased-locked loops (ADPLLs) are preferred over their analog counterparts in nanoscale CMOS technology due to their flexibility, configurability, small area and easy...

An Ultra-Low-Power ADPLL for WPAN Applications

RF PLLs for frequency synthesis and modulation consume a significant share of the total transceiver power, making sub-mW PLLs key to realize ulp WPAN radios. Compared to analog PLLs, all-digital phase-locked loops (ADPLLs) are preferred in nanoscale CMOS, as they offer benefits of smaller area, programmability, capability of extensive self...
