Abstract
Techniques for improving noise performance while processing signals received from an electrochemical sensor are provided. In an example, an interface circuit can include a first amplifier configured to provide a voltage to a counter electrode of an electrochemical sensor, a second amplifier configured to receive sensor information from a working electrode of the electrochemical sensor and to provide concentration information using the sensor information. In certain examples, an input of the first amplifier can be directly coupled to an input of the second amplifier to attenuate noise, of either the first amplifier or the second amplifier, within the concentration information provided by the second amplifier.
