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.
