Filtro de Quinta Orden (30 dB/Octava) (CIR5201S)

Written by: Newton C. Braga
Category: Banco de circuitos

 

     El filtro pasa-bajas mostrado en la figura utiliza dos amplificadores operacionales con JFET en la entrada para proporcionar una acción de corte de 30 dB por octava. Los valores de C1 y C2 se calculan según la frecuencia, según las fórmulas dadas junto al diagrama. Observe que es necesario tener una ganancia elevada y una alta impedancia de entrada para los operacionales para compensar la atenuación de las redes RC de ese filtro. También es necesario tener en cuenta los límites de frecuencia de los amplificadores operacionales usados. En realidad, estos circuitos se adaptan bien a la operación en frecuencias que no superen algunas decenas de kilohertz. Las fuentes de alimentación usadas para los amplificadores deben ser simétricas. Operacionales con JFET como los de la serie TLC y CA son los más indicados para esos circuitos.
