Artificial neural networks (ANNs) are information processing systems, with their design inspired by studies of the ability of the human brain to learn from observations and generalize by abstraction. Researchers have investigated a variety of important applications utilizing the ability of ANNs to perform the modeling and optimization of microwave components and circuits, such as high-speed very large-scale integration (VLSI) interconnects [1]-[3], spiral inductors [4], microwave field-effect transistors (FETs) [5], [6], heterojunction bipolar transistors [7], [8], high-electron mobility transistors [9], [10], filters [11]-[14], power amplifiers [15]-[17], oscillators [18], transmitters [19], receivers [20], digital predistortion [21], microelectromechanical systems [22], wireless power transfer [23], and multiphysics design [24], [25].
