1. A differential to single-ended converter comprising: a transconductance amplifier for receiving a differential voltage signal and converting the differential voltage signal to a differential current signal; a current mirror and buffer circuit, coupled to the transconductance amplifier, for conveying a differential current signal to a single-ended current signal and isolating the previous transconductance amplifier and the following transimpedance amplifier; and a transimpedance amplifier, coupled to the current mirror and buffer circuit, for receiving the single-ended current signal and converting the single-ended current signal to a single-ended voltage signal; wherein the current mirror and buffer circuit provides isolation between the transconductance amplifier and the transimpedance amplifier.
