Abstract

UN COMPARADOR DIFERENCIAL DE TIPO GENERAL (1) QUE TIENE UN VALOR UMBRAL QUE INCLUYE UNA SECCION PRINCIPAL (3) QUE CONTROLA EL VALOR UMBRAL DE LA SECCION ESCLAVA (2). LA SECCION ESCLAVA QUEDA CONTROLADA POR UNAS CORRIENTES DE POLARIZACION DETERMINADAS SUSTANCIALMENTE POR UNAS POLARIZACIONES FIJAS (VC + DELTA/2, VC DELTA/2) APLICADAS A LA SECCION PRINCIPAL, SIENDO LA DIFERENCIA ENTRE LAS POLARIZACIONES SUSTANCIALMENTE IGUAL AL VALOR UMBRAL DEL COMPARADOR. EL COMPARADOR GENERA UNA SALIDA (OUT+, OUT-) CUANDO LAS SEÑALES DE ENTRADA (IN+, IN-) SOBREPASAN DIFERENCIALMENTE EL VALOR UMBRAL.
