A 1.2-V current-mode RMS-to-DC converter based on a novel two-quadrant electronically simulated MOS translinear loop
Martincorena Arraiza, Maite
; Cruz Blas, Carlos Aristóteles de la ; Algueta-Miguel, Jose M. ; López Martín, Antonio (IEEE, 2020)
Artículo / Artikulua 
A novel current-mode CMOS RMS-to-DC converter using translinear techniques is introduced. It is based on a squarer/divider cell that is implemented using an electronically simulated loop with a novel biasing scheme that ... -
AC amplifiers with ultra-low corner frequency by using bootstrapping
Martincorena Arraiza, Maite ; Carlosena García, Alfonso ; Cruz Blas, Carlos Aristóteles de la ; López Martín, Antonio (Institution of Engineering and Technology, 2021)
Artículo / Artikulua
A novel architecture for an AC (i.e. high-pass) amplifier is proposed allowing a drastic reduction of the cutoff frequency to the sub-Hertz range. It builds upon the classic AC configuration with a high gain amplifier and ... -
AC coupled amplifier with a resistance multiplier technique for ultra-low frequency operation
Martincorena Arraiza, Maite ; Cruz Blas, Carlos Aristóteles de la ; Carlosena García, Alfonso ; López Martín, Antonio (Elsevier, 2022)
Artículo / Artikulua
This paper proposes a novel, tunable AC coupled capacitive feedback amplifier, exhibiting an ultra-low high pass corner frequency. This is accomplished by actively boosting the output resistive value of a MOS transistor ... -
A family of alternating current amplifiers for ultra-low frequency operation
Martincorena Arraiza, Maite ; Carlosena García, Alfonso ; Cruz Blas, Carlos Aristóteles de la ; Beloso Legarra, Javier ; López Martín, Antonio (Wiley, 2021)
Artículo / Artikulua
A family of capacitively coupled alternating current (AC) amplifiers featuring ultra-low (below 1 Hz) corner frequency is presented. This is achieved by using high-gain devices which actively boost feedback resistance and ... -
Fault detection of planetary gears based on signal space constellations
Martincorena Arraiza, Maite ; Cruz Blas, Carlos Aristóteles de la ; López Martín, Antonio ; Molina Vicuña, Cristian; Matías Maestro, Ignacio (MDPI, 2022)
Artículo / Artikulua
A new method to process the vibration signal acquired by an accelerometer placed in a planetary gearbox housing is proposed, which is useful to detect potential faults. The method is based on the phenomenological model and ... -
Microelectronic design for internet of things in hostile environments
Martincorena Arraiza, Maite (2023)
Tesis doctoral / Doktoretza tesia
Esta tesis presenta técnicas innovadoras de baja tensión, baja potencia y baja frecuencia utilizadas para diseñar nuevos bloques de circuitos (como amplificadores, filtros y convertidores RMS-DC) adecuados para aplicaciones ... -
Micropower class AB low-pass analog filter based on the super-source follower
Martincorena Arraiza, Maite ; Cruz Blas, Carlos Aristóteles de la ; López Martín, Antonio ; Carlosena García, Alfonso (IEEE, 2022)
Artículo / Artikulua
An improved class AB version of the super source follower is used to implement a compact and power-efficient second order analog low-pass filter. The proposed circuit achieves a 41% power reduction as well as an improvement ... -
Very-low frequency capacitively coupled AC amplifier with a current feedback operational amplifier
Beloso Legarra, Javier ; Cruz Blas, Carlos Aristóteles de la ; Carlosena García, Alfonso ; Martincorena Arraiza, Maite (Wiley, 2023)
Artículo / Artikulua
In this paper, we propose the idea of using transimpedance amplifiers, in lieu of operational amplifiers (OAs) or transconductance amplifiers (OTAs) to design capacitively coupled AC amplifiers. The idea is demonstrated ...
