Zusammenfassung:A third-order multi-channel incremental ADC with a 5-level quantizer is presented. An optimal decimation filter is used which minimizes the weighted sum of the thermal and quantization output noises. Digital correction is used to suppress mismatches in the multi-bit DAC. The prototype obtained a signal-to-noise-and-distortion ratio of 81.5 dB, within a total of 21.7 kHz signal bandwidth at a 10 MHz sampling frequency. The total power consumption for 20 channels is 6.7 mW.
