A 0.35 mum double-poly CMOS 16 b SAR A/D converter uses self-calibration techniques to obtain frac12 LSB INL. The differential and single-ended THD at 1Msample/s are 101dB and 96 dB, respectively. Each ADC consumes 20 mW at 3 V and occupies 2.9 mm2 active area, resulting in a 0.9 pJ/b FOM. The chip includes 3 ADCs, 2 DACs, 8051-microcontroller, CAN controller, DMA controller, 64 K flash memory and 4 K RAM occupying 26 mm2.
