Abstract
UN CIRCUITO DE COMPENSACION DE TEMPERATURA (26) SE UTILIZA PARA PROPORCIONAR UNA SEÑAL DE REFERENCIA EN UN BUCLE DE CONTROL DE GANANCIA ANTICIPATIVO (28). CON UNA DISPOSICION TAL, SE PROPORCIONA EL CONTROL DE GANANCIA EN DONDE SE MINIMIZAN LAS VARIACIONES DE UNA SEÑAL DE SALIDA DE UN CIRCUITO AMPLIFICADOR (10) DEBIDAS AL CAMBIO DE CARACTERISTICAS DE LOS ELEMENTOS DEL AMPLIFICADOR (12, 18) DEL CIRCUITO DEL AMPLIFICADOR (10) CAUSADAS POR LA TEMPERATURA AMBIENTAL O UNA VARIACION DEL NIVEL DE SEÑAL DE ENTRADA. UN ACOPLADOR (14) SUMINISTRA PARTE DE LA SEÑAL DE ENTRADA AMPLIFICADA (12) A UN DETECTOR (20) SEGUIDA POR UN FILTRO DE PASO BAJO (22) QUE SUMINISTRA UNA ENTRADA DE UN AMPLIFICADOR DIFERENCIAL (24) QUE RECIBE LA SEÑAL DE REFERENCIA Y SUMINISTRA UNA SEÑAL DE CONTROL A UN ATENUADOR CONTROLABLE (16).
