WebConsiderations for high-speed configurable-bandwidth time-interleaved digital delta-sigma modulators and synthesis in 28 nm UTBB FDSOI Web27 May 2004 · SNR is a calculated value that represents the ratio of rms signal to rms noise. You then multiply the log 10 of this ratio by 20 to derive SNR in decibels. As I mention above, an ADC’s ideal SNR equals 6.02N+1.76 dB, where N is the number of bits. You derive this formula by first defining the rms signal.
