This work presents a novel compact CMOS potentiostat-designed circuit for an electrochemical cell. The proposed topology functions as interface, controlling the polarization of voltage signals at sensor electrodes and facilitating current measurement during oxidation-reduction process analyzed solution. potentiostat, designed technology, comprises two-stage amplifier, two mirror blocks coupled to this push-pull output stage. method cyclic voltammetry is employed, operating within range ±0.8 V scan rates 10 mV/s, 25 100 250 mV/s. capable reading currents ranging from µA 500 µA. Experimental results were obtained using potassium ferrocyanide
