Multilayer Capacitor and Inductor Modeling and Analysis for Passive Component Development

Abstract

The increase in popularity and growth of wireless communication has inevitably newlineboosted multilayer integration technology. Using multilayer technology, passive newlinecomponents like inductors and capacitors are fabricated economically. The modeling newlineand analysis of multilayer passive component is a frontline research topic. Modeling newlineand analysis of multi-layered passive components are essentially done to develop a newlinecompact, low cost, and small size component for RF/Microwave applications. The newlinepassive components such as spiral inductor (SPI) and interdigital capacitor (IDC) are newlinecritical and necessary parts of RF/Microwave circuits like oscillators, filters, phase newlineshifters, low noise amplifiers, and impedance matching circuits. newlineIn the work carried out, the physical parameters of passive components are modeled newlineand optimized to achieve desired electrical characteristics such as inductance, newlinecapacitance, Q-factor, insertion loss (S21) and return loss (S11). The electromagnetic newline(EM) simulation of the modeled structures using NI/AWR tool is also performed, and newlinecharacteristic graphs are plotted for the analysis. The modeled EM structure of passive newlinecomponents and filter circuits are fabricated on multilayer RT/Duroid HTC6035 newlinesubstrate material. newlineThe modeled multilayer square spiral inductors and interdigital capacitors are newlineevaluated with 57 samples of different geometry of the physical parameters. The newlineimproved electrical characteristics are observed in the evaluated models. The VI newlineobservations of physical parameters with new values were made through simulation newlineand are found to be better than the existing designs. This observation reveals that the newlineperformance of the passive components is improvised over the current designs. newlineThe developed passive components are used to design low pass, high pass, and band newlinepass filters to test the performance. It was found that the new design has better newlineperformances. The designs were simulated first and then fabricated to observe their newlineperformance practically. The result
