Dear,
I am using the attached schematic to simulate the effect of Decoupling capacitor (someone may call it bypass , anyway it does not really matter) on the reduction of the power supply current transient as probably known to all of you guys.
However, no matter how I change the value of Decap (C2 in the schematic), the Current see from the power supply (V1) and the Current flowing through the inverter (Pmos transistor) remain exactly the same, which means that the C2 does not supply the transient . It seems really strange, I do not know what is wrong with this setup ?
Hope someone can give me some hint ! thanks
Jeffrey
