Abstract

SE PRESENTA UN DISCRIMINADOR DE FRECUENCIA QUE CONSTA DE UN VARIADOR DE FASE (3) PARA VARIAR UNA FASE DE UNA SEÑAL DE FI, UN MULTIPLICADOR (2) PARA MULTIPLICAR ANALOGICAMENTE LA SEÑAL DE FI Y LA SEÑAL DE SALIDA DEL VARIADOR DE FASE (3). LA SEÑAL RESULTANTE ASI OBTENIDA ES UNA CORRIENTE DIFERENCIAL. UN CIRCUITO DE ESPEJO DE CORRIENTE (M1-M6) FORMA UNA CORRIENTE DIFERENCIAL DE LA SALIDA DIFERENCIAL DEL MULTIPLICADOR (2); UN CIRCUITO INVERSOR (4) QUE ES ACTIVADO POR LA CORRIENTE DIFERENCIAL ASI FORMADA Y UN FILTRO DE PASO BAJO (5) INTEGRA LA SEÑAL DE SALIDA DEL CIRCUITO INVERSOR (4). ESTE DISCRIMINADOR DE FRECUENCIA TIPO CUADRATURA SE PUEDE REALIZAR COMO UN CIRCUITO INTEGRADO DE TECNOLOGIA MOS COMPLEMENTARIA.
