Abstract: Disclosed is a reconfigurable amplifier and an amplification method thereof, the amplifier includes an input selector, a first amplifying circuit, and a second amplifying circuit. The input selector is configured to select one of a voltage input and a current input based on a voltage measurement mode and a current measurement mode. The first amplifying circuit includes a first load element, and is configured to apply a voltage corresponding to the voltage input to the first load element in the voltage measurement mode and receive the current input in the current measurement mode and block a current flowing through the first load element. The second amplifying circuit is configured to mirror a current flowing through the first amplifying circuit in response to one of the voltage input and the current input and generate an output voltage based on the mirrored current.
