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 ...
Super class AB RFC OTA with adaptive local common-mode feedback
(Institution of Engineering and Technology, 2018)
info:eu-repo/semantics/article,
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 ...
Folded Cascode OTA with 5540 MHzpF/mA FoM
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
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
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
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 ...
Power efficient simple technique to convert a reset-and-hold into a true-sample-and-hold using an auxiliary output stage
(IEEE, 2020)
info:eu-repo/semantics/article,
A technique to implement true-sample-and-hold circuits that hold the output for almost the entire clock cycle without resetting to zero is introduced, alleviating the slew rate requirement on the op-amp. It is based on a ...
