摘要
Systems and methods for hematocrit measurement are provided. The present disclosure provides systems and methods for a low power and low-cost utilization of a microprocessor to capture hematocrit measurements for a blood glucose meter. The systems and methods include an electronic meter for performing a diagnostic test on a sample applied to a test strip inserted. The electronic meter can include a low cost low power microcontroller for capturing the hematocrit measurements. The microcontroller includes trans-impedance amplifiers (TIAs) configured to read a current over the test strip to generate a response waveform, an analog-to-digital (ADC) converter to convert the response waveform into a digital value, a peak detector circuit configured to capture peak current magnitude of the response waveform, and a peak detector circuit configured to capture a peak current time
