Resumen:
Many
electronic devices present nonlinear characteristics, which are often difficult
to express analytically. Generally it is easier to perform measurements of the
device parameters than to develop an analytical model of its behavior. As
Neural Networks can be used to learn a system dynamics from input-output data
only, we have developed a Neural Network model which reproduces the nonlinear behavior
of an electronic device, in particular a Field-Effect Transistor (FET), using
simulation data. However, electronic devices nonlinear analysis requires an
analytical model (i.e. an equation representing the current-voltage
relationship), described as a closed-form function, that allows to draw
conclusions about the device, such as the Volterra series model. In this work,
we want to show how the neural model and the analytical Volterra series model
of the transistor are totally equivalent. Therefore, we show here how it is
possible to build an analytical expression for a device nonlinearity, the
Volterra series, with parameters of a standard Neural Network, trained with the
device measurements or simulation data.
