Hi, I am currently conducting an FFT simulation for a 3-bit Flash ADC with a sampling rate of 10MHz, but I am encountering significant spectral leakage that degrades performance. I have used 2048 sampling points and ensured that the sampling period is a multiple of the signal's period. Despite these precautions, the spectral leakage remains an issue. I would appreciate any guidance on additional measures I can take to fix this problem. I am curious whether the issue lies with the circuit, such as the preamplifier or comparator, or if it is related to the setup of the FFT simulation.
Thanks!
Thanks!
