Abstract:

A fully integrated WiMedia v1.2 UWB PHY (radio plus digital baseband) covering all TFC codes has been realized in a baseline 65 nm CMOS process. The PHY features also detect and avoidance (DAA) capability. The inductorless design uses a single RF signal path to cover band groups 1, 3 and 6. Per band group only 2 fast settling all-digital PLLs generate the three required LO frequencies in a so-called `ping-pong' configuration. Each band group uses dedicated digitally controlled RC ring-based oscillators. The EVM for 480 MBps is below -24 dB and the sensitivity is below -81 dBm for 53 Mb/s. The IIP3 for maximum gain setting is better than -4 dBm. For the 480 Mb/s data rate the PHY draws 383 mW in receive mode and 312 mW in transmit mode from 1.2 V supply. The SoC measures 3.3×3.3 mm2.
