Claim 29:
30. A method of determining a glucose level comprising:
applying, using sensor electronics, a cyclic control signal to a glucose sensor configured to be positioned transcutaneously on a body of a user with a portion of the glucose sensor in contact with a bodily fluid, wherein the glucose sensor comprises a plurality of electrodes, including at least one work electrode and a reference electrode, each of which are electrically and communicatively coupled with the sensor electronics;
measuring, using the sensor electronics, a first response to the cyclic control signal applied to the glucose sensor during a first portion of the cyclic control signal and a second response to the cyclic control signal during a second portion of the cyclic control signal;
determining, using the sensor electronics, an estimated sensor parameter based on the first measured response to the cyclic control signal and the second measured response to the cyclic control signal;
receiving, using the sensor electronics, a sensor data signal from the glucose sensor; and
determining, using the sensor electronics, a calibrated glucose value based on the received sensor data signal and the estimated sensor parameter.
