Energy-efficient amplifiers based on quasi-floating gate techniques
(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 ...
Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
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
(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 ...

(MDPI, 2020)
info:eu-repo/semantics/article,
Aspirin (ASA) has attracted wide interest of numerous scientists worldwide thanks to its chemopreventive and chemotherapeutic effects, particularly in colorectal cancer (CRC). Incorporation of selenium (Se) atom into ASA ...
Eating behavior, physical activity and exercise training: a randomized controlled trial in young healthy adults
(MDPI, 2020)
info:eu-repo/semantics/article,
Regular physical activity (PA) is an important part of the treatment of several medical conditions, including overweight and obesity, in which there may be a weakened appetite control. Eating behaviour traits influence ...
