PAN Yin-song, ZHANG Ren-fu, LI Xiang-quan, et al. Design of CMOS potentiostat based on microarray biosensor[J]. 2009, 28(3): 80-82+85. DOI: 10.13873/j.1000-97872009.03.009.
a CMOS potentiostat circuit is designed.A potentiostat structure is used that shared a common half circuit among all of the amplifiers
layout area and power consumption of readout circuit are reduced.Simulation is carried out with 0.6 μm CMOS process by Spectre emulator.The simulation results show that good linear relation between input and output and broad dynamic respond range of biosensor is obtained by using current integral circuit with potentiostat.
