AbstractA differential to single-ended converter, which is composed of a transconductance amplifier, a current mirror and buffer circuit and a transimpedance stage, is disclosed. A differential voltage signal is provided to the inputs of the transconductance amplifier and converted to a differential current signal. The current mirror and buffer circuit serves as a differential to single-ended current conveyer and isolates the transconductance stage and the following transimpedance stage. Finally, the single-ended current signal is provided to the input of the transimpedance stage and converted to a single-ended current signal.
