Abstract: THE PRESENT INVENTION RELATES TO AN ANALYTE SENSOR SYSTEM (100) TO DETERMINE CONCENTRATION OF A TARGETED ANALYTE IN A BODY FLUID. THE ANALYTE SENSOR SYSTEM (100) COMPRISES OF A SENSING DEVICE (110), A CURRENT MEASUREMENT CIRCUIT (130) CONNECTED TO THE SENSING DEVICE (110), A BIASING CIRCUIT (150) CONNECTED TO THE SENSING DEVICE (110), AND A VOLTAGE REFERENCE CIRCUIT (170) CONNECTED TO THE SENSING DEVICE (110). THE ANALYTE SENSOR SYSTEM (100) SELECTIVELY OXIDIZES THE TARGETED ANALYTE AND CONSEQUENTLY, PRODUCES AN OXIDATION CURRENT WHICH IS AN INDICATIVE OF THE CONCENTRATION OF THE TARGETED ANALYTE IN THE BODY FLUID.
