1. A method of processing analyte sensor signals, comprising:

  • applying a poise voltage to an analyte sensor;

    while applying the poise voltage to the analyte sensor, applying a control signal to the analyte sensor;

    measuring a response signal based on the poise voltage and the control signal from the analyte sensor;

    estimating, with one or more processors, a sensor sensitivity based on a predetermined calculated correlation to a variance in the measured response; and

    determining a calibrated analyte value based on the estimated sensor sensitivity;

    wherein the control signal comprises a time-varying perturbation signal that provides for the analyte sensor a duty cycle and the variance is determined from a transient response of the analyte sensor to the control signal during the duty cycle.
