The designed low-noise OTA is a modified version of a standard folded-cascode topology. The OTA is biased in such way that the currents of the individual transistors in the second folded branch M7-M12 of transistors are only a small fraction of the current in the input differential pair transistors M1 and M2. -The designed low-noise OTA is a modified version of a standard folded-cascode topology.
