Method and system for providing calibration of an analyte sensor in an analyte monitoring system
First Claim
Patent Images
1. A method of calibrating an analyte sensor, comprising:
- detecting a measured response of an analyte sensor to a perturbation signal;
determining a variance in the detected measured response;
comparing the variance in the detected measured response with a table that correlates one or more predetermined calculated measured response differences for the analyte sensor with one or more sensor sensitivities;
estimating, with a processor, a sensor sensitivity based on the variance in the detected measured response, wherein the estimation of the sensor sensitivity is based at least in part on the comparison of the variance in the detected measured response with the table that correlates one or more predetermined calculated measured response differences for the analyte sensor with one or more sensor sensitivities; and
applying the estimated sensor sensitivity to a signal from the analyte sensor.
