Abstract

Electro-analytical (E-chem) biosensors offer unique advantages over widely used optical biosensors and can be considered ideal for low-cost, mass-deployable point-of-care (PoC) diagnostic devices [1]. They possess fully electronic and real-time transduction methods and require little or no external instrumentation. Despite these advantages, two fundamental challenges have hampered broad adoption of E-chem biosensors: 1C design and transducer (surface) material suitability. E-chem sensors require both low-noise and high detection dynamic range (DDR) front-end circuits and must also accommodate electrode-electrolyte interfaces with significant PVT variations and temporal drifts [2]-[5]. The absence of CMOS-compatible bio-electronic interfaces with adequate chemical and thermal stability has been another impediment [6].
