Hi,
I am using 12 bit ADC with ENOB of 11.2bits to measure DC voltage. On firmware, I am taking 16 averages. Assuming additive white Gaussian noise, the ENOB improves by approximately 2 bits.
My claim is that the resolution of the ADC now become 14bits with accuracy of 13.2bits. So I believe that this ADC can measure smaller voltages than the ADC before averaging.
Am I correct??
If this method can be used to improve resolution, there is no need to buy higher resolution ADC; we can just use fast 12bit ADC and take large number of averages.
Thank you
