ABSTRACT:
High-performance operational transconductance amplifier monolithically integrable with CMOS technology comprising a differential input stage connected to a pair of cascode stages and a differential output stage. The output stage comprises two output transistors whose gate terminals are connected to nodes for connection of the input stage and the cascode stages. The output terminals of the amplifier are connected to intermediate nodes of the cascode stages through capacitors.
