Claim Text:
1. An amplifier comprising: a pair of transistors each having a pair of input terminals between which an input voltage signal is applied and each having a pair of output terminals between which a current flows in proportion to the input voltage signal, the input terminals and the output terminals sharing a common terminal such that each of the input terminals and the output terminals comprise the common terminal and a corresponding non-common terminal; a feedback circuit electrically connected at opposite ends thereof between the non-common output terminal and the non-common input terminal of a closed-loop one of the transistors, the opposite ends of the feedback circuit being electrically disconnected from any two terminals of an open-loop one of the transistors; an input port comprising a signal-carrying input terminal and a ground terminal between which a single-ended input signal is accepted, the input terminal of the input port being electrically connected to the non-common input terminal of both of the transistors; and an output port comprising a positive terminal and a negative terminal between which a differential output signal is provided, the positive terminal of the output port being electrically connected to the non-common terminal of the open-loop transistor and the negative terminal of the output port being electrically connected to the non-common output terminal of the closed-loop transistor.
