Hi
I simulate 8-bit current-steering DAC. Fsine=prime_number*Fsample/(number_of_dft_bins). I'm doing a transient simulation on Spectre, stop_time=(number_of_dft_bins/Fsample), and then using dft function on the output, to produce the SNR from SpectrumMeas. I don't understand what exactly affects the noise floor, how does the dft calculate the noise floor? because changing the number of transistors in the DAC, fro example, changes the SNR. Appreciate any help, Iris
