Oversampled Analog-to-Digital conversion has been demonstrated to be an effective technique for high resolution analog-to-digital (A/D) conversion that is tolerant to process imperfections. The area and power budget of conventionally designed oversampled analog-to-digital converters has precluded their application from areas where a large number of low frequency signals need to be converted simultaneously. A new oversampled A/D design methodology is proposed to cut the area and power budget per channel of an oversampled analog-to-digital converter. The design and implementation of a 16-channel oversampled analog-to-digital converter is presented which can be used as the core of the multichannel data acquisition system. The prototype achieved 80 dB of signal-to-noise-plus-distortion over 1 kHz, [minus]80 dB of crosstalk and used less than 20 mW of power excluding clock generation.
