Abstract
Circuitry for processing an analyte signal obtained from an electrochemical cell, the circuitry comprising: a converter, comprising: a first converter input configured to receive the analyte signal; a second converter input; and a converter output configured to output a converted analyte signal, the converter configured to generate the converted analyte signal in dependence on the analyte signal; a loop filter configured to filter a signal derived from the converted analyte signal to obtain a filtered analyte signal at a filter output; and a feedback path between the filter output and the second converter input.
Claims31
Circuitry for processing an analyte signal obtained from an electrochemical cell,
- the circuitry comprising:
- a converter, comprising:
- a first converter input configured to receive the analyte signal;
- a second converter input;
- and
- a converter output configured to output a converted analyte signal, the converter configured to generate the converted analyte signal in dependence on the analyte signal;
