N2 - In this paper, a current sensing mechanism for biochemical sensor is presented. The sensing circuit consists of current conveyor, current mirror, current range detection circuit, and current to digital converter. The chip can be integrated in a potentiostat system. This work is implemented in TSMC 0.18-μm CMOS process, and the area is 0.5625 mm2. The measured current ranges from 20 μA to 1200 μA with average linear correlation (R-squared) of 0.9986. The power consumption of the proposed circuit is 1.41 mW from 1.8 V power supply.
