A Quadrature VCO with Phase Noise Optimization for Wide Tuning Triple Band Frequency Generation
Hechen Wang, Fa Foster Dai
This paper presents an analytical model on quadrature VCO (QVCO) phase noise performance as well as a wide-tuning triple band QVCO RFIC design. The phase noise model demonstrates t…
