Especially for Digital/Analog mixed circuits---A/D converting circuits, the requirements for converting precision and speed are becoming more and more, leading to more requirements for low power dissipation.
Auger spectra analysis shows that the least dissipation factor of capacitor is 0.1-0.3% (1kHz) and the temperature coefficient is 201.5±3.5ppm/℃(-40~70℃) when Pn: Mn: O = 30: 20: 50.
By analyzing the flip chip structure of high power InGaN blue +YAG fluorescence powders white light emitting diode (LED), it shows that it can improve the luminous and heat dissipation efficacy.
This low noise amplifier provides a forward gain of 26.3 dB with a noise figure of only 1.9 dB while drawing about 5.8 mA current from 2.5 V supply voltage. The stack-style structure,which reuses the bias current,guarantees low power dissipation(about 14.5 mW) and high reverse isolation of about-40 dB.This LNA achieves IIP3 of-15 dBm and 1-dB compression of-25 dBm.
In the present paper, we deal with the long-time behavior of dissipative partial differential equations, and we construct the approximate inertial manifolds for the nonlinear Schr?dinger equation with a zero order dissipation.
The relative dielectric constant εr and the dissipation factor tgδ of the PZT thin films were measured with an LCR meter and were found to be 158 and 0.04-0.005, respectively.
The sap flow density, water consumption, and related environmental factors were also measured using thermal dissipation method and ICT-2000TE (Transpiration-Environment) automatic measuring system for tree transpiration and environmental factors.
This paper describes an ultraviolet photopreionized highpressure CO2 laser. This laser employs a cable-coupled, parallel-discharge preioniized circuit and a main discharge circuit, which share a common power supply. It has a number of advantages, such as less energy dissipation, good stability, simplicity of configuration and so on. This laser can be operated at 8-12 atm with a peak power output of about 20 MW. Continuous tuning over total frequency range of 100cm-1 on the P and R branches of 9.4μand ...
A new high speed integrated logic has been described. Instead of a single type of cell gate which is used in most logic IC's, the new logic here described is based on several types of basic cells to synthesize a logic system. Therefore, the threshold characteristic will not be the common requirement for each type of cell gates. The main logic unit in DYL is a very high-speed linear AND-OR gate made with simple technology (without threshold). A four-bit full adder carry chain specimen has been developed with...
Described here is a new style, cardiac pacing system—an implantable pacemaker with the programmability of parameters. It consists of a programmer and an implantable pacemaker with a digital memorial element. Whenever an adjustment is neccessary, the pacemaker can be manipulated to a new stable state with the programmer emitting a series of coded pulses toward it. The process of adjustment is quick and noninvasive.The pacemaker is made by combining a CMOS circuit with monolithic integralted circuits into a h...
