Low‐voltage fully differential difference transconductance amplifier

IET Circuits, Devices & Systems, 2017
A new complementary metal–oxide–semiconductor (CMOS) structure for fully differential difference transconductance amplifier (FDDTA) is presented in this study. Thanks to using the non‐conventional quasi‐floating‐gate (QFG) technique the circuit is capable to work under low‐voltage supply of 0.6 V with extended input voltage range and with class AB ...

A Fully Differential Difference Transconductance Amplifier Topology Based on CMOS Inverters

Electronics, 2023
This manuscript presents a fully differential difference transconductance amplifier (FDDTA) architecture based on CMOS inverters. Designed in a 130-nm CMOS process it operates in weak inversion when supplied with 0.25 V. In addition, the FDDTA requires no supplementary external calibration circuit, like tail current or bias voltage sources, since it ...
