Abstract

See full text

According to an aspect of the present inventive concept there is provided a reconfigurable sensor circuit comprising:

    an input stage including a first input terminal and a second input terminal, andan amplification stage including: a first amplifier having a non-inverting input, an inverting input and an output connected to the inverting input of the first amplifier via a first resistor,a second amplifier having a non-inverting input, an inverting input and an output connected to the inverting input of the second amplifier via a second resistor, and first switching circuitry adapted to be arranged in a first state, wherein the amplification stage is in a differential amplifier configuration, and in a second state, wherein the amplification stage is in a transimpedance amplifier configuration,wherein, in the differential amplifier configuration, the first amplifier and the second amplifier are together configured as a differential amplifier connected to the first and the second input terminals, andwherein, in the transimpedance amplifier configuration, at least the first amplifier is configured as a transimpedance amplifier connected to the first input terminal.
