Ultramicroscopy, 2014
Using low beam energies in a (scanning) transmission electron microscope (S/TEM) has numerous advantages over higher beam energies. We discuss the performance of commonly available electron microscopes when being operated at reduced beam energies.

Low Power, Low Voltage, Low Drop-Out On-chip Voltage Regulator
2020Extremely low power, low voltage complete on-chip low drop-out voltage regulator (LDO) is presented. The LDO receives an unregulated supply of 0.5–1 V and regulates it to 0.4 V nominal output utilizing a 0.1 V on-chip reference voltage. A load capacitor of just 1pf is assumed to be present at LDO output. Designed voltage reference and complete LDO were

Pediatrics, 1971
The hazards accompanying the increasing use of line-operated electrical devices for diagnosis and therapy as well as the more common hospital appliances such as electrically operated beds, television sets, radio sets, and so forth have been recently reemphasized.1 Most physicians are aware of the dangers of alternating current (60 Hz AC) or of high ...

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1995
This paper reviews the design of analog filters at low supply voltage. In particular, the main focus is on switched capacitor and g/sub m/-C type filters because, at the present time, they have the greatest commercial importance. SC implementations are discussed in the context of low frequency high precision applications while g/sub m/-C ...

Ultra-Low-Voltage Electrowetting
The Journal of Physical Chemistry C, 2010Electrovariable optical components based on liquid/liquid interfaces encompass microfluidic lenses and mirrors, fiber-optic switches, and display elements. These devices function on the basis of the electrowetting effect, where a liquid interface is deformed by an applied electric field. Existing electrovariable lenses use electrowetting on dielectrics;

Journal of Circuits, Systems and Computers, 1995
This paper summarizes some of the current solutions to fulfil the requirements of the new low voltage power systems. On one hand, microelectronics evolution demands lower supply voltage. On the other hand, the portability of the new communication systems demands lighter and smaller power electronics.

A low voltage low output impedance CMOS bandgap voltage reference
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013A low voltage bandgap architecture is proposed. The opamp in the proposed bandgap is used for both generating the output reference voltage (Vref) and achieving low output impedance. To allow Vref to have different values within the supply voltage limits, a transconductor is proposed and used in conjunction with the opamp to supply the biasing currents ...

A low voltage CMOS low drop-out voltage regulator
SPIE Proceedings, 2009A low voltage implementation of a CMOS Low Drop-Out voltage regulator (LDO) is presented. The requirement of low voltage devices is crucial for portable devices that require extensive computations in a low power environment. The LDO is implemented in 90nm generic CMOS technology. It generates a fixed 0.8V from a 2.5V supply which on discharging goes

Low-voltage differential amplifier
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009A low-voltage differential amplifier constructed by bulk-driven PMOS transistors is proposed in this paper. A local positive feedback is utilized that boosts the input transconductance and improve the noise performance. The input common-mode range is also compared to the gate-driven counterpart.
