Abstract: Circuitry for processing an analyte signal obtained from an electrochemical cell, the circuitry comprising: measurement circuitry having a first measurement input coupled to a first electrode of the electrochemical cell, the measurement circuitry configured to convert the analyte signal at the first measurement input to a first analog output signal; an analog-to-digital converter (ADC) having an first ADC input for receiving the first analog output signal, the ADC configured to convert the first analog output signal to a first digital output signal at an ADC output; compensation circuitry configured in a measurement mode to: apply a first compensation to the first digital output signal to obtain a first compensated digital output signal, the first compensation to compensate for non-linearity in the ADC; and apply a second compensation to the first compensated digital output signal to obtain a second compensated digital output signal, the second compensation to compensate for non-linearity in the measurement c

Abstract: A Time of Flight (ToF) system includes an emitter array comprising one or more emitters configured to emit optical signals, a detector array comprising a plurality of detectors that are configured to output respective detection signals responsive to the optical signals that are reflected from a target, and a control circuit. The control circuit is configured to: control the emitter array to emit a first optical signal; and provide a plurality of activation signals to a subset of the plurality of detectors responsive to the first optical signal to activate respective ones of the detectors of the subset for a first duration to generate detection signals associated with the first optical signal. Respective ones of the plurality of activation signals are offset from one another by respective time offsets.
