1. A system for providing analyte sensor calibration, comprising:

  • a first analyte sensor configured for fluid contact with an analyte under a skin layer to monitor an analyte level;

    a second analyte sensor configured for fluid contact with the analyte under the skin layer to monitor the analyte level; and

    one or more processors in signal communication with the first analyte sensor and the second analyte sensor, the one or more processors configured to receive data associated with the monitored analyte level from the first analyte sensor, and to calibrate the second analyte sensor with reference to the received data associated with the monitored analyte level received from the first analyte sensor by determining a scaling factor that includes comparing data from the first analyte sensor with the data from the second analyte sensor and based on an initial scaling factor with a predetermined level of average error between the data of the first analyte sensor and the data of the second analyte sensor, applying the determined scaling factor to the data from the second analyte sensor, and determining a correlation level of signals from the first analyte sensor and the signals from the second analyte sensor.
