ADC Basics, Part 4: Using Delta-Sigma ADCs in Your Design

The delta-sigma ADC tackles the application demands of a slow analog signal that requires a high signal-to-noise-ratio (SNR) and wide dynamic range. But, the delta-sigma converter is not the only ...

Using Delta-Sigma Can Be As Easy As ADC (Part 5)

My last column showed how a single-stage delta-sigma modulator (DSM) produces an output that is a sum of the low pass-filtered input signal and the high pass-filtered quantization noise (see “Part 4,” ...
