Analysis and design of quadrature oscillators

The following features of Analysis and Design of Quadrature Oscillators make it different from the existing literature on electronic oscillators: (1) focuson quadrature oscillators with accurate quadrature and low phase-noise, required by modern communication systems; (2) a detailed comparative study of quadrature LC and RC oscillators, including cross-coupled LC quasi-sinusoidal oscillators, cross-coupled RC relaxation oscillators, a quadrature RC oscillator-mixer, and two-integrator oscillators; (3) a thorough investigation of the effect of mismatches on the phase-error and the phase-noise; (4) the conclusion that quadrature RC oscillators can be a practical alternative to LC oscillators when area and cost should be minimized (in cross-coupled RC oscillators both the quadrature-error and phase-noise are reduced, whereas in LC oscillators the coupling increases the phase-noise). The focus is on Quadrature Oscillators rather than on single oscillators Technology independent theoretical results arepresented using a structured design approach Experimental results are given for integrated circuits in the GHz range A detailed comparative study of quadrature LC and RC oscillators is presented INDICE: From the contents 1 - Introduction. 2 - Transceiver Architectures and RF Blocks. 3 - Quadrature Relaxation Oscillator. 4 - Quadrature Oscillator-Mixer. 5 - Quadrature LC-Oscillator. 6 - Two-Integrator Oscillator. 7 - Measurement Results. 8 - Conclusions and Future Research.
