Abstract
Circuitry for processing an analyte signal obtained from an electrochemical cell, the circuitry comprising: a first analog-to-digital converter (ADC) configured to generate a first digital output based on the analyte signal; a second ADC configured to generate a second digital output based on the analyte signal; and control circuitry configured to control generation of the second digital output by the second ADC based on the first digital output from the first ADC.
