A New Temperature Compensation Method for a 2.5 GHz Integrated VCO

The demand for high speed wireless data communication has been increasing tremendously. Wireless applications typically require VCO's (Voltage Controlled Oscillator's) having low power consumption, low phase noise, small size and low cost. The size, the cost requirements and the low phase noise make an integrated oscillator in a standard CMOS (Complementary Metal-Oxide-Semiconductor) process with an on-chip resonance LC tank, a good choice. Rings oscillators have poor phase noise performance disqualifies them in many of today's wireless applications. In the recent years fully integrated cross coupled voltage controlled LC tank oscillators received attention.
