Hi MacGyver,
So you think that case 3 is the best in my case - ADC sampling and LP on the acquired samples before they added in the accumulator for averaging.

Hi,
Thank you for the idea - see attached the file where are shown 3 cases:
1. ADC with hardware LP filter on the input is acquiring multiple samples. The final result is the average value of all samples
2. ADC without hardware LP filter is acquiring multiple samples. The final result is the...
Hi MacGyver,
Thank you for the response.
In oversampling the gain in the SNR and/or the additional bits comes after applying LP filtering on the measured samples. So my concerns are about the LP filtering
Hi,
I'll put it other words - say I have in one case 10x bigger capacitor 10*Cs where I accumulate 10 charge transfers and then measure the voltage. In other case I have small capacitor Cs and measure 10 times the voltage. In both cases the measured voltage like value is the same.
The question...

Hi,
One theoreitical question about signal integration.
Imagine that you have 10 bit ADC which measures the changing voltage on some capacitor. The signal is quite noise so there are mainly two approaches:
1. Increase the RC constant on the system...
