  • Patent number: 11764735
    Abstract: A biosensor for an analyte monitoring system. In one embodiment, the biosensor includes a cascode common source transimpedance amplifier circuit, an analog to digital converter, and an output circuit. The cascode common source transimpedance amplifier circuit is configured to receive an electrical current generated by an electrochemical reaction of an analyte on a test strip. The cascode common source transimpedance amplifier circuit is also configured to convert the electrical current to an analog voltage signal. The analog to digital converter is configured to convert the analog voltage signal to a digital voltage signal. The output circuit is configured to transmit a signal indicating a measured level of the analyte based on the digital voltage signal.

  • Publication number: 20230172495
    Abstract: The present disclosure presents glucose sensing methods and systems. One such system comprises an electrospun-nanofibrous-membrane (ENFM)-based amperometric glucose sensor integrated on a silicon chip, in which the glucose sensor has a working electrode, a reference electrode, and a counter electrode, wherein the working electrode comprises an ENFM-based sensing electrode. The system further comprises a potentiostat circuit integrated on the silicon chip such that the potentiostat circuit comprises a voltage control unit to control a voltage difference between the working electrode and the reference electrode and a transimpedance amplifier to measure a current flow between the working electrode and the counter electrode, in which a strength of the current flow corresponds to an amount of glucose present in a sample of blood on the glucose sensor.
