摘要：

This paper proposed design of a low power potentiostat for electrochemical biosensing with high input dynamic range. A current compensation circuit is proposed to extend the detection range. Chopper stabilization potentiostat is used to suppress the low-frequency noise, realizing a high accuracy. The proposed design was fabricated in 0.18-mu m CMOS process occupying a silicon area of 0.43 mm(2). The experimental results show a dynamic range of 68 dB with a power consumption of 105 mu W.
