Artificial Neural Networking Improves PA Design
Mar 1, 2006
By Jarno Kyhälä Artificial neural networking can be used to aid the design work of the device such as a power amplifier. This paper will discuss the ANN model generator implemented in the APLAC simulator, and show how ANN can be more efficient than conventional interpolation. It will also demonstrate the usefulness of ANN in electronics design using an example of optimizing a matching network for a power amplifier....
