A two-port negative-resistance oscillator, shown in Figure 2, is characterized by the oscillator transistor's S parameters, terminating network impedance [Z.
He also advocates using CAD simulation techniques with a wide variety of oscillators, covering their theories and history, their characteristics, tuned-circuit oscillators, crystal oscillators, negative-resistance oscillators and nonsinusoidal oscillators.
