A Dual-Channel Wide Input Range Interface Circuit For Electrochemical Amperometric Sensors |
Abstract | ||
---|---|---|
A wide input range, compliant with electrochemical amperometric sensors interface circuit is proposed in this paper. The interface circuit consists of a potentiostat which is fabricated on PCB board and an interface ASIC which is realized in a single chip. The ASIC employs current integrator (CI) and transimpedance amplifier (TIA) to deal with the input current in the order of nA and mu A separately, achieving the advantage of wide input range and high resolution. An incremental sigma-delta ADC is employed to digitize the transferring signal to achieve the feature of one-to-one mapping between input and output. The ASIC is fabricated in 0.18 mu m 1P5M mixed-signal CMOS process, has a dynamic range of 120 dB, and consumes 4.2 mA. |
