1. A circuitry for processing an analyte signal obtained from an electrochemical cell, the circuitry comprising:
a first signal path between a first electrode of the electrochemical cell and a first input of an analog-to-digital converter (ADC) circuit, the first signal path comprising a first gain stage configured to convert the analyte signal to a first analog signal;
a second signal path between the first electrode and a second input of the ADC circuit, the second signal path comprising a second gain stage configured to convert the analyte signal to a second analog signal; and
switching circuitry configured to selectively couple the first electrode to the first input of the ADC circuit.
