摘要：
An ultra-low power 4.3 GHz Synchronous Oscillator (SO) is presented, integrated in a 0.25 mum BiCMOS SiGe technology, to act as the RF loop of an UMTS double-loop synthesizer. This SO is tunable in order to counteract technology discrepancies. Hence, the synchronization range is smaller, reducing unwanted synchronization and improving the frequency generation accuracy. This 1.8V SO provides a -115dBc/Hz phase noise at 100 kHz offset, consuming only 3.6 mW.
