Abstract

MEZCLADOR DIFERENCIAL (DM) QUE SE UTILIZA EN UN TRANSMISOR DE RADIO TELECOMUNICACION QUE FUNCIONA CON UNA TENSION DE ALIMENTACION DE 3 VOLTIOS, E INCLUYE UNA PAREJA DE AMPLIFICADORES DIFERENCIALES BIPOLARES INTERCONECTADOS DE SILICONA (A;B) PARA RECIBIR UNA PRIMERA TENSION DE ENTRADA (LO) A UNA ELEVADA FRECUENCIA, UNA PAREJA DE GENERADORES DE CORRIENTE (I1; I2) Y UN CONVERTIDOR MOS DE TENSION A CORRIENTE (VIC) PARA RECIBIR UNA SEGUNDA TENSION DE ENTRADA (VIN) A UNA FRECUENCIA INFERIOR. EL CONVERTIDOR SE ADAPTA PARA CONVERTIR UNA TENSION DE BAJA FRECUENCIA EN UNA CORRIENTE DIFERENCIAL (INN) Y ESTA ACOPLADO A LOS NUDOS DE LOS AMPLIFICADORES Y DE LOS GENERADORES DE CORRIENTE. EL CONVERTIDOR INCLUYE ADEMAS UN CIRCUITO AMPLIFICADOR DIFERENCIAL REGULADO (P1; P2) AL QUE SE APLICA LA TENSION DE ENTRADA DE BAJA FRECUENCIA (VIN) MEDIANTE RESISTENCIAS (R/1; R/2) Y QUE ESTA ACOPLADO A LOS TERMINALES DE SUMINISTRO (VCC;GND) DEL MEZCLADOR MEDIANTE DOS PAREJAS DE GENERADORES DE CORRIENTE DE INTENSIDAD CONSTANTE (PB1, PB2; NB1, NB2) RESPECTIVAMENTE. PREFERENTEMENTE, SE APLICA UN TERMINAL DE TENSION DE REFERENCIA DE INTENSIDAD CONSTANTE AL ELECTRODO COMPUERTA DE LOS TRANSISTORES (P1;P2) DEL CIRCUITO AMPLIFICADOR MEDIANTE UN AMPLIFICADOR OPERATIVO (O1; O2).
