<p>The circuit has an operational amplifier (3) with inverting and non-inverting inputs (31,32), and an output which provides the overall output of the amplifier configuration. The non-inverting input is connected to a first reference potential (P1). The output is connected to the inverting input via a resistor (1), A current follower (8) has an input stage having a current input, including a second resistor (2) connected to input (E) of the overall amplifier arrangement, and an output stage having a current output, which is connected to the inverting input of the operational amplifier. The input and output stages of the current follower are coupled to respective reference potentials (P1,P2).</p> |
