Abstract :
This paper presents a low power current-mirror based potentiostat for implantable glucose sensor tags. With a potential-control loop and an error-reduction loop, the potentiostat can accurately capture the weak current from glucose sensors. The design has been implemented using SMIC 0.13 μm 1P8M CMOS process. According to the test results, the liner correlation coefficient of the potentiostat is 0.999936 with the current range of 0~40nA, and the power consumption of the potentiostat is 3.6 μW.
