Voltammogramwith on-chip carbon WE, and external CE (Pt) and RE (Ag/AgCl). Electrodes are immersed in 200 $\mathsf{\mu }$ M dopamine. In this experiment, the scan rate of triangular waveform is 50 $\mathrm{m}\mathrm{V}{\mathrm{s}}^{-1}$ and the feedback resistor of the TIA is 100 $\mathrm{k}\Omega$ .
