Fully differential CMOS transconductance-transimpedance wide-band amplifier

摘要

A fully differential, wide-band transconductance-transimpedance 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 a transimpedance stage for generating an output voltage signal from the amplified current signal generated in the current gain stage.
