Abstract
A 90nm CMOS, 9.2-12GHz digital fractional-N synthesizer for WLAN/WiMax is described. Stochastic calibration of time to digital conversion and a VCO phase noise minimization algorithm are used to achieve <;-35dBc integrated phase nose (100Hz to 10MHz), in the 5-6GHz band with spurs below -60dBc.
