    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


    A fully integrated 2.4 GHz differential voltage-controlled oscillator (VCO) is presented. The circuit can be tuned from 2.1 to 3.6 GHz without any component changes or re-dimensioning. The phase noise of the oscillator is -102 dBc/Hz at 1 MHz offset from 2.4 GHz. The design has been fabricated using a 0.35 µm SiGe BiCMOS process and the circuit area of the prototype is 0.9 mm2 including on-chip inductors. The prototype chip draws 3.1 mA current from a 2 V supply.
