Abstract
Circuitería para la introducción de condiciones iniciales en sistemas basados en amplificadores operacionales. La presente invención describe un procedimiento y una circuitería para acelerar el arranque de los osciladores y reducir el transitorio necesario para alcanzar el estado estacionario. Aunque la invención es especialmente indicada para osciladores, puede ser aplicada a cualquier tipo de circuito con amplificadores operacionales, tanto lineales como no-lineales, y en particular por medio del uso de un amplificador modificado, llamado "sw- opamp". Dicho amplificador es capaz de operar como amplificador normal o como buffer en función de una señal de control digital. El sw-opamp en el modo buffer junto con un nivel apropiado de DC se usan para inicializar el circuito en el punto deseado y/o conveniente para el arranque del circuito.
