Energy-efficient amplifiers based on quasi-floating gate techniques
López Martín, Antonio
; Garde Luque, María Pilar ; Algueta-Miguel, Jose M. ; Beloso Legarra, Javier ; González Carvajal, Ramón; Ramírez-Angulo, Jaime (MDPI, 2021)
Artículo / Artikulua 
Energy efficiency is a key requirement in the design of amplifiers for modern wireless applications. The use of quasi-floating gate (QFG) transistors is a very convenient approach to achieve such energy efficiency. We ... -
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 ... -
Gain-boosted super class AB OTAs based on nested local feedback
Beloso Legarra, Javier ; Cruz Blas, Carlos Aristóteles de la ; López Martín, Antonio ; Ramírez-Angulo, Jaime (IEEE, 2021)
Artículo / Artikulua
A new approach to design super class AB operational transcon-ductance amplifiers (OTAs) with enhanced large-signal and small-signal performance is presented. It is based on employing two nested positive and negative feedback ... -
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 ...
