An enhanced gain-bandwidth class-AB miller op-amp with 23,800 MHz pF/mW FOM, 11-16 current efficiency and wide range of resistive and capacitive loads driving capability

Paul, Anindita; Ramírez-Angulo, Jaime; Díaz Sánchez, Alejandro; López Martín, Antonio ; González Carvajal, Ramón; Li, Frank X. (IEEE, 2021) Artículo / Artikulua

A compact power-efficient class-AB Miller op-amp is introduced. It uses a simple auxiliary circuit that enhances the op-amp's gain-bandwidth product and helps to drive a wide range of capacitive and resistive loads with ...
Super-gain-boosted AB-AB fully differential Miller op-amp with 156dB open-loop gain and 174MV/V MHZ pF/uW figure of merit in 130nm CMOS technology

Paul, Anindita; Ramírez-Angulo, Jaime; Díaz Sánchez, Alejandro; López Martín, Antonio ; González Carvajal, Ramón; Li, Frank X. (IEEE, 2021) Artículo / Artikulua

A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used ...
