Abstract

ESTADO DE LA TECNICA: SE CONOCEN EN GENERAL AMPLIFICADORES SUMADORES CON AMPLIFICADORES OPERATIVOS REACOPLADOS. PROBLEMA TECNICO: LOS FACTORES DE PONDERACION SON COCIENTES DE LA RESISTENCIA DE REACOPLAMIENTO COMUN A TODOS LOS SUMANDOS Y DE LAS RESISTENCIAS PREVIAS INDIVIDUALES. SOLAMENTE LA RESISTENCIA DE REACOPLAMIENTO ACTUA DIRECTAMENTE PROPORCIONAL. LAS RESISTENCIAS PREVIAS INDIVIDUALES ACTUAN INVERSAMENTE PROPORCIONALES. LA FORMACION DE FACTORES DE PONDERACION COMPLEJOS PREDETERMINADOS ES DIFICIL. EL PROBLEMA APARECE, POR EJEMPLO, EN CASO DE INTERFASES DE DOS HILOS-CUATRO HILOS. IDEA FUNDAMENTAL: AMPLIFICADORES SUMADORES DE DOS FASES, SUMANDOSE LA PRIMERA FASE (VS2'') CON FACTORES REALES Y REALIZANDOSE FACTORES COMPLEJOS EN LA PRIMERA FASE (VS1''). VENTAJAS: SE PUEDEN REALIZAR INTERFASES SIMETRICAS TERRESTRES Y ASIMETRICAS TERRESTRES DE FORMA IGUALMENTE SENCILLA CON UNA SOLA CAPACIDAD . SE PUEDEN EVALUAR SEÑALES DE CADENCIA SINCRONICA DE MANERA SENCILLA (SSE); ES POSIBLE UNA SEÑALIZACIONDE CADENCIA SINCRONICA (DS).
