| Popis: |
This paper describes a fully integrated Silicon Germanium (SiGe)Voltage Controlled Oscillator (VCO)chip with 19%tuning range and low phase noise suitable for 10-Gb/s fiber optic transceivers and X-band applications.It consists of two switchable externally enabled VCO ’s.The total chip tuning range is 9.2-11.1GHz when the varactor control voltage varies from 0 to 3.0V and the measured phase noise is –87dBc/Hz at 100KHz offset from carrier.The typical current consumption is 8mA for the VCO core at 3.3V voltage supply.The chip is implemented in SiGe BiCMOS7 technology intended for high volume production. |
