Claim 22:
23. A glucose monitoring system comprising:
a glucose sensor comprising a plurality of electrodes, including at least one work electrode and a reference electrode, wherein the glucose sensor is configured to be positioned transcutaneously with a portion of the glucose sensor in contact with a bodily fluid, wherein the glucose sensor is configured to produce a sensor data signal corresponding to a level of a glucose in the bodily fluid; and
a transmitter unit comprising sensor electronics electrically and communicatively coupled with the plurality of electrodes, wherein the transmitter unit is configured to be positioned on a body of a user, and wherein the sensor electronics are configured to perform operations comprising:
applying a cyclic control signal to the glucose sensor;
measuring 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 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 a sensor data signal from the glucose sensor; and
determining a calibrated glucose value based on the received sensor data signal and the estimated sensor parameter.
