An enhanced ultrasonic communication system based on piezoelectric transducers for monitoring of goods in cargo containers is presented. The proposed system consists of several sensors placed inside the container, whose ... -
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 ... -

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 ... -
Super-gain-boosted miller op-amp based on nested regulated cascode techniques with FoMAOLDC =24,614kV/V.MHz.pF/µWatt
Paul, Anindita; Ramírez-Angulo, Jaime; López Martín, Antonio ; González Carvajal, Ramón; Díaz Sánchez, Alejandro (IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena
A simple technique to greatly enhance the DC open-loop gain of a Miller op-amp is introduced here. It is based on the utilization of nested regulated cascode amplifiers. It uses conventional Miller compensation and does ... -
Two-stage OTA with all subthreshold MOSFETs and optimum GBW to DC-current ratio
Beloso Legarra, Javier ; Grasso, A.; López Martín, Antonio ; Palumbo, Gaetano; Pennisi, Salvatore (IEEE, 2022)
Artículo / Artikulua
An approach for the design of two-stage classAB OTAs with sub-1µA current consumption is proposed and demonstrated. The approach employs MOS transistors operating in subthreshold and allows maximum gain-bandwidth product ... -
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 ...
