ABSTRACT:
A fully differential, wide-band transconductance-transimpedence amplifier with a tuneable gain is disclosed. The amplifier includes a transconductance stage for generating a current signal from an inputted voltage signal. The amplifier also has a current gain stage for amplifying the current signal generated by the transconductance stage. Additionally, the amplifier includes as transimpedance stage for generating an output voltage signal from the amplified current signal generated in the current gain stage.
