1. A method of processing signals from a glucose sensor, comprising:

  • coupling a first amplifier to a signal source;

    coupling a second amplifier to the first amplifier, wherein a first output signal from the first amplifier is a predetermined ratio of a second output signal from the second amplifier, the first output signal and the second output signal associated with a monitored glucose level;

    operatively coupling an analog to digital (ND) converter to the second amplifier;

    comparing signals at an output terminal of the second amplifier to a predetermined threshold value; and

    processing a signal associated with the signals at the second amplifier output terminal when another signal at the second amplifier output terminal exceeds the predetermined threshold value.
