Nonlinear Circuit Analysis via Perturbation Methods and Hardware Prototyping

Abstract EN

Nonlinear signal processing is necessary in many emerging applications where form factor and power are at a premium.

In order to make such complex computation feasible under these constraints, it is necessary to implement the signal processors as analog circuits.

Since analog circuit design is largely based on a linear systems perspective, new tools are being introduced to circuit designers that allow them to understand and exploit circuit nonlinearity for useful processing.

This paper discusses two such tools, which represent nonlinear circuit behavior in a graphical way, making it easy to develop a qualitative appreciation for the circuits under study.
