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 16-528 mu A, DNL and INL of +/- 0.5 LSB and +/- 1.0 LSB, conversion rate of 10 M samples, and power dissipation of 94.4 mW with a power supply of 5 V. The effective chip area excluding t he pads is 1.8 mmx2.4 mm.
