1. A continuous glucose sensor, the sensor comprising:

  • a first working electrode comprising a first electroactive surface disposed beneath an active enzymatic portion of a sensor membrane, wherein the first working electrode is configured to generate a first signal having a first noise component related to a noise-causing species; and

    a second working electrode comprising a second electroactive surface disposed beneath an inactive-enzymatic or a non-enzymatic portion of the sensor membrane, wherein the second working electrode is configured to generate a second signal having a second noise component related to the noise-causing species;

    wherein the first electroactive surface and the second electroactive surface are each dimensioned to integrate at least one signal generated by a plurality of local point sources that produce the noise-causing species, such that the first noise component and the second noise component are substantially equivalent.
