Abstract
A low-power 1.2 V CMOS chopper-stabilized analog front-end integrated circuit (IC) for glucose monitoring is presented in this letter. The operating parameters of the IC, including reference voltage in potentiostat, current offset, output gain, and offset, are fully programmable. The IC is fabricated using 0.13- $\mu \text{m}$ CMOS technology, has an active area of $1.4\,\,\text {mm} \times 4.3$ mm, and its power consumption is $30.2~\mu \text{W}$ . Furthermore, a chopper-stabilized open-loop transimpedance amplifier is proposed for low-power and low-noise implementation. The integrated input-referred current noise is 260 pArms with a bandwidth of 100 Hz.
