Abstract
This paper describes a 10 bit CMOS current-mode A/D converter with a curren t predictor and a modular current reference circuit. A current predictor an d a modular current reference circuit are employed to reduce the number of comparator and reference current mirrors and consequently to decrease a pow er dissipation. The 10 bit current-mode A/D converter is fabricated by the 0.6 mu m n-well double poly/triple metal CMOS technology. The measurement r esults show the input current range of 16 mu A to 528 mu A, DNL and INL of +/-0.5 LSB and +/-1.0 LSB, conversion rate of 10 Msamples, and power dissip ation of 94.4mW with a power supply of 5 V. The effective chip area excludi ng the pads is 1.8 mm x 2.4 mm.
