Abstract
DOS TRANSISTORES (T1, T2) TIENEN SUS BASES CONECTADAS A LAS ENTRADAS RESPECTIVAS (A, B). EL COLECTOR DE UN TRANSISTOR SE UNE A UN VOLTAJE DE SUMINISTRO (VA) A TRAVES DE UN RESONADOR (L1, C1) Y TAMBIEN A LA BASE DEL OTRO TRANSISTOR POR MEDIO DE UN CONDENSADOR (C2), MIENTRAS EL OTRO TRANSISTOR TIENE SU COLECTOR DIRECTAMENTE UNIDO AL VOLTAJE DE SUMINISTRO. LOS EMISORES DE AMBOS TRANSISTORES ESTAN CONECTADOS ENTRE SI Y A TIERRA A TRAVES DE UN RESISTOR COMUN (R3). PARA LA COMPARACION DE MULTIPLES SEÑALES DE ENTRADA, ESTAS PUEDEN SER MUESTREADAS Y CONVERTIDAS EN CONVERTIDORES PARALELO/SERIE (PSA, PSB), CADA UNO DE LOS CUALES TIENE UNA ENTRADA EN PARALELO RESPECTIVA (A A AN, B1 A BN) PARA RECIBIR DE MANERA HOMOGENEA LAS SEÑALES BAJO MONITORIZACION, Y CADA UNA TIENE UNA LINEA DE SALIDA SIMPLE (UA, UB) QUE SE DIRIGE A UNA DE LAS DOS ENTRADAS PRINCIPALES (A, B). LOS DOS CONVERTIDORES ESTAN CONTROLADOS POR RESPECTIVAS SEÑALES QUE HACEN POSIBLE LA CONVERSION (ACQA, ACQB) QUE ESTAN SINCRONIZADAS ENTRE SI Y QUE TIENEN UN PERIODO (TC) MAS CORTO QUE EL PERIODO MAS CORTO DE LAS SEÑALES BAJO MONITORIZACION (TP) DIVIDIDAS POR EL NUMERO DE SEÑALES BAJO MONITORIZACION MAS 2.
