Abstract
An amplifier capable of operating in multiple modes may include (a) first and second voltage inputs and (b) first and second current outputs that have substantially the same amplitude and polarity. Preferably, the inputs and outputs of the amplifier will have high impedances. The amplifier may operate in a first mode—and function as an operational amplifier—when the first and second current outputs are coupled together. The amplifier may operate in a second mode—and function as a type-2 current conveyor—when the second current output is coupled to the second voltage input. The amplifier may additionally include a third current output that has an amplitude that is substantially the same as the amplitudes of the first and second outputs and a polarity that is substantially opposite to the polarities of the first and second outputs. In this configuration the amplifier may function as a four-terminal floating nullor.
