Low-Power Wordline Voltage Generator for Low-Voltage Flash Memory
2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006Wordline voltage generating circuit with high speed active mode and low power standby mode is proposed. In the active mode, two different ring oscillators with high clock frequency (fCLK) 170 MHz, and low clock frequency (fCLK) 25 MHz which is also the operating frequency of the entire circuit, are employed.

A low supply-dependence fully-MOSFET voltage reference for low-voltage and low-power
APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008A low supply-dependence fully-MOSFET voltage reference for low-voltage and low-power is presented. It compensates for the temperature dependence of a current based on gate-source voltage of a MOSFET operating in subthreshold region with a low supply-dependence PTAT current, and exhibits very low supply-dependence for supply voltage.

Low-voltage linear voltage regulator suitable for memories
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004In this communication a low-voltage linear voltage regulator in CMOS technology is presented. It is based on a two class-AB gain stage and, hence, does not suffer from internal slew-rate limitation when very large load capacitances are used. The linear regulator suitable for memory application was designed in a 0.35 /spl mu/m standard CMOS technology ...

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

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;

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
