An error amplifier is most commonly encountered in feedback unidirectional voltage control circuits where the sampled output voltage of the circuit under control is fed back and compared to a stable reference voltage. Any difference between the two generates a compensating error voltage which tends to move the output voltage towards the design specification.
I have construct an error amplifier using MOSFET. By injecting the input V-=5V and V+= 6.0893V and simulate through PSpice. The output i got is 1.3922V.
Is it simply by substracting the V+ and V- to get the output. If so, why the voltage is abit higher compare to the calculation?
You forgot to attach your circuit so how am I supposed to see what it is???
Is it a voltage regulator?
What are you using as its accurate reference voltage?
