Abstract [en]

A calibration technique for compensation of the generated phase error at the band hopping instant is proposed for a fast-hopping DLL-based injection-locked frequency synthesizer for WiMedia UWB band group #1. This technique makes the accuracy of the phase error compensation immune to process variations and so the VCDL nonlinearity. Simulated in 65-nm CMOS technology, the average synthesizer hopping time is 4 ns for all process corners. The phase noise performance at 1 MHz offset from 4488 MHz carrier is -121 dBc/Hz and the adjacent spur level from the Monte Carlo simulation is -37 dBc. Excluding the CML divider, the synthesizer consumes 7.7 mW from a 1.2 V supply.
