Inductive and Capacitive Effects in a Second Order Low-Pass Filter Constructed in PCB

Abstract

In this article an experimental analysis of the capacitive and inductive effects in a printed circuit board using a two pole RC filter widely known, with several wide and length size traces is presented. The ideal frequency transfer response graphs and graphics that include inductive and capacitive effects due to the size of signal paths in a microstrip printed circuit board are presented. The frequency response plot obtained experimentally and the plots obtained simulating the electric equivalent circuit proposed using the SPICE, SERENADE and MATLAB programs are also shown. The error obtained was less than the 2%
