Abstract
According to one embodiment, an amplification circuit includes first and second differential amplification circuits, each having an output connected to an output terminal and a feedback resistor connected between the output and a negative input of the respective differential amplification circuit. The amplification circuit includes a switching circuit that receives a first signal on first input terminal and a second signal on a second input terminal and includes set of switches that is configured to apply the first and second signals to the first and second differential amplification circuits such that in a first switching state an amplified voltage difference of the first and second signals is available between the two output terminals, and in a second switching state an amplified current difference of the first and second signals is available between the two output terminals.
