A fully integrated output capacitor, MOS-only reference, 55mnm low-dropout regulator (LDO) with optimized area and power is proposed in this letter for system-on-chip (SoC) self-powered Internet of Things (IoT) applications. The small capacitor saves both cost, but brings challenges to the system’s stability transient response. In order improve system area, a dynamic attenuation buffer along ne...

One of the most popular power management regulators is low drop-out voltage regulator (LDO). LDOs have different specifications such as supply rejection (PSR) over frequencies, stability load ranges, inrush current spike flows through input supply, and consumption. In this work, we present a LDO design with techniques for PSR improvement across frequencies. The presented in work low-power small...

Single-tank simultaneous nitrification and denitrification (SNdN) processes can potentially eliminate the need for separate tanks and for recycling mixed liquor from oxic nitrifying zones to the typically upstream anoxic zones for denitrification. However, the conditions involved are more susceptible to sludge bulking by excessive growth of filamentous bacteria. This study was aimed at identify...

Galectins, a family of structurally related carbohydrate-binding proteins, contribute to different events associated with cancer biology, including apoptosis, homotypic cell aggregation, angiogenesis and tumor-immune escape. To interfere with galectin-carbohydrate interactions during tumor progression, a current challenge is the design of specific galectin inhibitors for therapeutic purposes. H...

This paper presents the design of low-dropout volt-age regulators (LDO) using nanowire tunnel field-effect tran-sistors (TFETs) and MOSFET. The devices are mod-eled lookup tables implemented with experimental measures TFETs different source compositions (Si, SiGe Ge) In order to compare designs, transistors differential amplifier in all LDOs is biased gm/ID = 8 V-1 a load 1 μA 10-pF. It shown t...

Abstract To improve the whole characteristic of LDO, a low quiescent current structure high voltage LDO with self-regulation impedance buffer and bandgap amplifier is presented in this paper. With proposed, function reference error can be achieved simultaneously, which efficiently reduce consumption. The load capacitor as small 0.47 µ F by using compensation scheme. has been implemented 0.18 m ...
