Summary: | A CMOS 1 MSps 10 bit charge-redistribution SAR ADC processes single-ended signals with 1 LSB accuracy selectable input ranges up to supply voltage. A new DAC architecture presents the benefits of a differential approach while sampling single-ended signals. Thanks to new low power design solutions in the ADC comparator and the built-in reference buffer, the total ADC power consumption is only 2.7 mW at 2.4 V supply and 1 MSps. The active area is 0.4 mm/sup 2/ in a 0.35 /spl mu/m CMOS process. |
