Power Valve: for low power operation and low stand-by power
The concept of Power Valve is presented. It consists of power switch transistors and control circuits, which give variable impedance to the power supply. The circuit controls the internal power supply voltage of logic circuits and reduces the voltage swing of signals. An experiment using a 130-nm test chip showed a 36.0% operating power reduction for a

Effect of Contact Angle Hysteresis on Evaporation Dynamics of a Sessile Drop on a Heated Surface [PDF]
Contact angle hysteresis (CAH) is a significant factor affecting the drop motion on solid substrates. A model of CAH is introduced to explore the influence of CAH on the dynamics of a sessile drop on a uniformly heated surface, and a two-dimensional ...

Ultralow-Power SOTB CMOS Technology Operating Down to 0.4 V
Ultralow-voltage (ULV) CMOS will be a core building block of highly energy efficient electronics. Although the operation at the minimum energy point (MEP) is effective for ULP CMOS circuits, its slow operation speed often means that it is not used in ...

Review on Coupled Thermo-Hydraulic Performance of Nanofluids and Microchannels
As electronic components continue to be miniaturized, the heat flux density continues to increase. Scholars have proposed the use of microchannel heat sinks (MCHS) to dissipate heat from devices with high heat flux density, and have pointed out that the ...
