| abstract | The potential shifter includes a voltage regulator, a current mirror, a capacitor, a comparator, a current source, and a counter. The voltage regulator maintains the voltage on the working electrode of the electrochemical sensor. The current mirror generates a mirror current that mirrors the current input from the working electrode. The capacitors are alternately charged by the mirror current to increase the capacitor voltage in a ratio related to the magnitude of the current and are discharged by the control current to reduce the capacitor voltage. The comparator outputs a waveform including up and down transitions based on a change in the capacitor voltage. The current source generates a control current based on the waveform. The counter counts the number of up or down transitions in the waveform for a predetermined sampling period to produce a digital output. The digital output represents the magnitude of the input current. |
