Abstract

A 10 GHz fully integrated Voltage Controlled Oscillator ispresented. A 29.7% tuning range is achieved from a 2.5 V powersupply. The phase noise is -113 dBc/Hz at 600 kHz and -127 dBc/Hzat 3 MHz. The VCO is implemented in a 0.25 ìm 4 metal layerstandard CMOS technology. This design will be used to discussdesign and layout issues for high frequency LC-oscillators. Athorough analysis will be made of the contribution of the differentbuilding blocks to the performance of the total circuit.
