2.1 Time-domain noise analysis (transient noise)

The purpose of an electronic circuit is to process a signal containing useful information. This signal may contain disturbances introduced by the environment (outside the circuit) or by the operation of the circuit itself. In order to guarantee correct operation of the circuit, it may be necessary to control or at least quantify these disturbances, which are of various natures and origins; they may be deterministic or random.

In this section, we focus on the random disturbances introduced by the physical noise generated by the components in the circuits under analysis. This noise originates from the granular nature of the electric current, and is influenced by temperature, certain component parameters, or even...
