A 10 GHz SiGe BiCMOS phase-locked-loop frequency synthesizer

A SiGe BiCMOS phase-lock-loop circuit is presented. A maximum operational frequency of 10 GHz and a current consumption of 7.6 mA, i.e. 17 mW is demonstrated. For a 9 mW low power version, a maximum frequency of 4.7 GHz is determined. This demonstrates the speed and power advantage of the SiGe BiCMOS technology for wireless communications.
