4.1.1 Amplitude noise and phase noise

In oscillators, frequency multipliers, frequency dividers, and more generally in circuits using high-level signals (see box), modulations are generated in the non-linear circuit by the noise sources of the components used. We evaluate the noise power carried by these phase and amplitude modulations.

Why is a circuit non-linear?

In non-linear diagrams and in circuit dynamics...
