ABSTRACT:
A differential transimpedance amplifier (TIA) circuit comprises first, second, third, fourth, fifth and sixth transconductance amplifiers having an input, an output and first, second, third, fourth, fifth and sixth transconductance gains, respectively. A first resistance communicates with said third transconductance amplifier and with said second transconductance amplifier. A second resistance communicates with said third transconductance amplifier and said third transconductance amplifier. A third resistance communicates with said sixth transconductance amplifier and said fifth transconductance amplifier. A fourth resistance communicates with said sixth transconductance amplifier and with said sixth transconductance amplifier. A fifth resistance communicates with said third transconductance amplifier and said fourth transconductance amplifier. A sixth resistance communicates with said sixth transconductance amplifier and said first transconductance amplifier.
