Analysis of EMI Reduction Techniques on a PRBS Generator Board

Abstract

ForewordIn 2011, the Education and Student Activities Committee announced a student EMC hardware design competition [1]. The objective was to build a small PRBS (pseudo random binary sequence) generator circuit having minimal EMI with a given set of components without using shielding. The competition inspired student groups to systematically investigate the sources, the coupling paths and the antennas in a quali tative fashion for creating a minimal noise circuit with reasonable effort.
