Achieved 98 dB SNR with 1% capacitor mismatch and 50 ps jitter.

% PSD estimation [psd, f] = pwelch(y, hanning(1024), 512, 1024, fs); inband = f <= fB; snr = 10*log10(sum(psd(inband)) / sum(psd(~inband))); fprintf('SNR = %.1f dB\n', snr);

[ SNR_max \approx \frac32 \cdot \frac2L+1\pi^2L \cdot OSR^2L+1 \quad \text(for Lth-order, ideal) ]
