1. An analyte monitoring system, comprising:

  • an analyte sensor at least a portion of which is configured to be in fluid contact with an analyte, the analyte sensor configured to detect an analyte level;

    a transmitter unit including an analog interface operatively coupled to the analyte sensor and configured to receive one or more signals associated with the analyte level, the transmitter unit configured to transmit one or more data corresponding to the one or more signals associated with the analyte level, the transmitter unit further including a peak detection unit configured to detect a condition associated with a power source of the transmitter unit, the peak detection unit configured to electrically isolate the power source of the transmitter from the analog interface when the condition is detected; and

    a receiver unit configured to receive the one or more data corresponding to the one or more signals associated with the analyte level from the transmitter unit when the condition associated with the power source of the transmitter unit is detected;

    wherein the analog interface is configured to draw power from the peak detection circuit when the condition associated with the power source is detected and is isolated from the power source.
