Procedure for direct measurement of Common Mode Rejection

To measure the Common Mode Rejection (CMR) of an amplifier, it is necessary to carry out the measurements of the implemented and finished circuit, and then perform the measurement of its behavior in real operating conditions. This measurement is necessary to evaluate the susceptibility to conducted...

This measurement is necessary to evaluate the susceptibility to conducted electromagnetic interferences (conducted EMI) on the amplifier. In this work, a procedure of direct measurement of the CMR of an amplifier without altering the circuit is described. The measurements are verified by simulation with PSpice. Para medir el Rechazo en Modo Común (CMR) de un amplificador, es necesario llevar a cabo las mediciones del circuito implementado y terminado, y entonces realizar la medición de su comportamiento en condiciones de funcionamiento real. Esta medición es necesaria para evaluar la susceptibilidad a las interferencias electromagnéticas conducidas (EMI conducidas) sobre el amplificador. En este trabajo, se describe un procedimiento de medición directa del CMR de un amplificador sin alterar el circuito. Las mediciones se verifican mediante simulación con PSpice. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/27 10.37537/rev.elektron.2.1.27.2018 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/27/40 https://elektron.fi.uba.ar/elektron/article/view/27/154 Derechos de autor 2017 Julio Zola, Enrique Zothner, Juan Kelly Elektron Journal; Vol. 2 No. 1 (2018); 39-46 Revista Elektron; Vol. 2 Núm. 1 (2018); 39-46 Revista Elektron; v. 2 n. 1 (2018); 39-46 2525-0159 2525-0159 CMRR EMI Operational amplifier CMRR EMI amplificador operacional Procedure for direct measurement of Common Mode Rejection Procedimiento para medición directa del Rechazo de Modo Común info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=27_oai
