It’s a counterintuitive result that you might need to add noise to an input signal to get the full benefits from oversampling in analog to digital conversion. [Paul Allen] steps us through a simple ...

Shown is a simplified continuous-time sigma-delta ADC model, comprising a sigma-delta modulator and a decimation filter. The DT-S? input structure typically implements switched capacitors, and CT-S?

It can be shown that for a PAM-4 link with Gaussian noise achieving 1E-12 BER, the SNR has to be 24.5 dB, but what does this mean? What’s the top consideration that network and data center SoC/systems ...
