Abstract :
A new successive-approximation analog-to-digital (A/D) converter is described. New interpolated C-R DAC, new R-ladder-steering decoder and constant-current comparator have been applied in the A/D converter. By adopting these techniques, high-resolution (12 bit accuracy) and high-speed conversion (1 MHz) with low power consumption (1 mW) has been realized. This chip has been fabricated by double metal and double polysilicon 0.8 μm CMOS process, and the die size is 2.4×1.7 mm 2
