1-V 15-μW 130-nm CMOS super class AB OTA
López Martín, Antonio
; Algueta-Miguel, Jose M. ; Garde Luque, María Pilar ; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena 
A super class AB recycling folded cascode amplifier in 130 nm CMOS is presented. It combines for the first time adaptive biasing of the differential input pair, nonlinear current mirrors with current starving and dynamic ... -
Folded Cascode OTA with 5540 MHzpF/mA FoM
Garde Luque, María Pilar ; López Martín, Antonio ; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2018)
Contribución a congreso / Biltzarrerako ekarpena
A micropower single-stage folded cascode amplifier able to drive a wide range of capacitive loads is presented. It features class AB operation and includes power-efficient adaptive biasing techniques, which provide enhanced ... -
On the optimal current followers for wide-swing current-efficient amplifiers
López Martín, Antonio ; Garde Luque, María Pilar ; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2018)
Contribución a congreso / Biltzarrerako ekarpena
The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed. Two basic current follower topologies are compared, and modifications of both followers to ... -
Super class AB RFC OTA using non-linear current mirrors
Garde Luque, María Pilar ; López Martín, Antonio ; Carvajal, Ramón G.; Galán, J.A.; Ramírez-Angulo, Jaime (Institution of Engineering and Technology, 2018)
Artículo / Artikulua
An alternative approach to the design of super class AB recycling folded cascode operational transconductance amplifiers is proposed. Instead of using local common-mode feedback for boosting dynamic currents, simple current ... -
Super class AB RFC OTA with adaptive local common-mode feedback
Garde Luque, María Pilar ; López Martín, Antonio ; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (Institution of Engineering and Technology, 2018)
Artículo / Artikulua
A super class AB recycling folded cascode operational transconductance amplifier is presented. It employs local common-mode feedback using two matched tuneable active resistors, allowing to adapt the amplifier to different ... -
Wide-swing class AB regulated cascode current mirror
Garde Luque, María Pilar ; López Martín, Antonio ; Cruz Blas, Carlos Aristóteles de la ; Carvajal, Ramón G.; Ramírez-Angulo, Jaime (IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena
A micropower regulated cascode CMOS current mirror is presented, combining floating gate and quasi floating gate MOS transistors to achieve both wide swing and class AB operation, respectively. Measurement results for a ...
