  • Signal readout circuit for amperometric sensor
    Patent number: 7663357
    Abstract: A signal readout circuit for amperometric sensor for reading a readout signal of a sensor includes an amplifier, a first transistor, a second transistor, and a first resistor. A negative input end of the amplifier receives an input voltage, and a positive input end of the amplifier is connected to a reference electrode of the sensor. Gates of the first transistor and the second transistor are connected to an output end of the amplifier, a drain of the first transistor is connected to a counter electrode of the sensor, and a drain of the second transistor is connected to the first resistor.
    Type: Grant
