Two methods of oscillator analysis and design are considered in this book. One method involves the open-loop gain and phase response versus frequency. This Bode response and nonlinear effects discussed later predict many aspects of oscillator performance. A second method considers the oscillator as a one-port with a negative real impedance to which a resonator is attached. The loop method provides a more complete and intuitive analysis while the negative resistance method is more suitable for broad tuning oscillators operating above several hundred megahertz.
