Abstract:

Nonlinearity is an inseparable part of analog and RF Integrated Circuits since it may cause distortion in the amplitude and the phase of the signal which will lead to the loss of information. Although nonlinear circuits are intensely sophisticated in nature, it is often possible to employ power series approximations to model the nonlinearity of them. However, there are special cases where those approximations are no longer valid. The purpose of this presentation is to provide an introduction to a method called Volterra series. Volterra series are defined to address the issue of dynamic nonlinearities which are not modelled in power series. These series are still approximations and are valid only for weakly nonlinear circuits but they cover a wide range of applications.
