He diseñado un simple circuito amplificador de audio. Cuando ejecuté la simulación con Time Domain Transient, fue capaz de producir una onda sinusoidal agradable con una amplificación de aproximadamente 20x usando la fuente de voltaje Vsin en un amplio rango de frecuencias. Sin embargo, cuando cambié la fuente de voltaje a Vac (0.1Vac, 0Vdc) e intenté ejecutar la simulación con AC Sweep / Noise, sigue devolviendo un valor de error no válido. Pero este mensaje de error es increíblemente vago y no tengo idea de qué parte está causando el error. He elegido el rango de frecuencia de 10 Hz a 10 MHz, 500 puntos / década. Mensaje de error devuelto de la simulación adjunta a continuación. Aprecio la ayuda.
