Circuito de Señal Triangular a Cuadrada

flux

A continuación te dejo un resumen de cómo se podría diseñar el circuito utilizando amplificadores operacionales:
  1. Generación de la onda triangular:
    • Se puede implementar un oscilador que genere inicialmente una onda cuadrada (por ejemplo, con un LM358 configurado con histéresis) y luego integrarla utilizando un circuito integrador (RC + amplificador operacional) para obtener la onda triangular.
    • Se deben añadir los componentes pasivos (resistencias y capacitores) necesarios para definir la frecuencia de oscilación y el rango de la señal.
  2. Conversión a onda cuadrada:
    • Se utiliza un segundo amplificador operacional, por ejemplo otro LM358 configurado como comparador.
    • Este comparador compara la onda triangular generada con un punto de referencia (que puede obtenerse a partir de un divisor de voltaje) y genera la onda cuadrada en la salida.
  3. Conexiones y alimentación:
    • Asegúrate de conectar cada etapa al Ground y de incluir decoupling capacitors para ambos amplificadores, siguiendo las recomendaciones de los datasheets.
Si deseas, puedo sugerirte los cambios al esquema agregando dos op-amps (por ejemplo, designados como [U1] y [U2]), el conjunto de resistencias y capacitores correspondientes, y las conexiones a tierra.
¿Quieres que prepare una sugerencia de actualización del esquema con esta configuración?
