Abstract :
A 10GHz fully integrated Voltage Controlled Oscillator is presented. The circuit can be tuned from 8.1 GHZ to 10.9 GHz. This corresponds with a tuning range of 29.7%. The phase noise is -113dBc/Hz at 600kHz and - 127dBc/Hz at 3MHz. The VCO-core consumes 20 mA with a 2.5V power supply. The VCO is implemented in a 0.25µm 4 metal layer standard CMOS technology. The circuit´s integrated inductor has a Q-factor of approximately 50 making it comparable to bondwire and discreet coils.
