Abstract

Ultra-low-power potentiostats, which perform high-precision current measurements for electrochemical biosensing, hold paramount importance in the development of health-monitoring wearables, point-of-care (PoC), and implantable diagnostics. In this application, the power budget is gravely limited (sub-μW), and the input current signal varies from pA to μA range, which corresponds to a dynamic range (DR) of >120dB [1, 2]. These requirements become more stringent in some applications, such as single-molecule biosensors, where the desired signal currents exist within the nA range amidst the backdrop of background currents in the nA-to-μA range [1], and millimeter-sized electrochemical sensors, where the power efficiency is crucial.
