摘要
The influence of flip-chip assembly on a 2.4-GHz fully integrated Voltage Controlled Oscillator (VCO) is studied. Oscillation frequency and phase noise differ by 17.7% and 9.4 dB, respectively, between flip-chip assembly and package. Measurement and simulation are compared and show excellent agreement. Mutual inductance is found to be the origin of the degradation of the inductor's characteristics. (C) 2004 Wiley Periodicals, Inc.
