Puerta Analógica OFF Alterna

00:17:56

Diseño de una puerta analógica para que presente un aislamiento de -68 dB (0.00039810 en lineal).
Es decir, el voltaje presente en la resistencia de carga, VLoad, será igual a 0.00039810*Vgenerador.

Si la fuente de 1MHz entrega 1 Voltio (Vgenerador = 1V), entonces el voltaje que cae en la resistencia de carga será:
VLoad = 0.00039810*1V = 0.00039810 V = 0.3981 mV

Para obtener un valor de aislamiento diferente es necesario ajustar el valor del condensador presente entre las dos fuentes de corriente.
