Abstract
A 10.5- to 11-GHz fully monolithic voltage controlled dilator circuit implemented in a standard SiGe bipolar technology is presented. An oscillator phase noise of -78 to -87 dBc/Hz is achieved at 100-kHz offset. The tuning range is close to 5% with an on-chip varactor-tuned resonator and for a control voltage of O to 3 V. The circuit draws less than 8 niA from a 3-V supply including the reference branch bias current.
