摘要：本文基于Matlab對(duì)約瑟夫森結(jié)（Josephson junction）RCSJ模型的交直流I-V特性及非線性混沌現(xiàn)象進(jìn)行數(shù)值模擬。通過計(jì)算機(jī)數(shù)值模擬得到該模型的非線性微分方程數(shù)值解，研究了RCSJ模型中各參量對(duì)約瑟夫森結(jié)的影響，進(jìn)而簡(jiǎn)要分析其I-V特性和非線性混沌現(xiàn)象的產(chǎn)生機(jī)理，繪制出約瑟夫森結(jié)的交直流I-V特性曲線、非線性微分方程的相圖及因其高度非線性而引起的通過倍周期分岔和陣發(fā)性原理進(jìn)入混沌狀態(tài)的分岔圖。 關(guān)鍵詞：超導(dǎo)器件 隧道效應(yīng) 約瑟夫森結(jié) 弱耦合 倍周期分岔 龐加萊截面 混沌

看到不少網(wǎng)友對(duì)COOLMOS感興趣，把自己收集整理的資料、個(gè)人理解發(fā)出來，與大家共享。個(gè)人理解不一定完全正確，僅供參考。COOLMOS（super junction）原理，與普通VDMOS的差異如下： 對(duì)于常規(guī)VDMOS器件結(jié)構(gòu)，大家都知道Rdson與BV這一對(duì)矛盾關(guān)系，要想提高BV，都是從減小EPI參雜濃度著手，但是外延層又是正向電流流通的通道，EPI參雜濃度減小了，電阻必然變大，Rdson就大了。所以對(duì)于普通VDMOS，兩者矛盾不可調(diào)和。8 X( ?1 B4 i* q: i但是對(duì)于COOLMOS，這個(gè)矛盾就不那么明顯了。通過設(shè)置一個(gè)深入EPI的的P區(qū)，大大提高了BV，同時(shí)對(duì)Rdson上不產(chǎn)生影響。為什么有了這個(gè)深入襯底的P區(qū)，就能大大提高耐壓呢？

Many thermal metrics exist for integrated circuit (IC) packages ranging from θja to Ψjt.Often, these thermal metrics are misapplied by customers who try to use them to estimate junction temperatures in their systems.

多遠(yuǎn)程二極管溫度傳感器-Design Considerations for pc thermal management Multiple RDTS (remote diode temperature sensing) provides the most accurate method of sensing an IC’s junction temperature. It overcomes thermal gradient and placement issues encountered when trying to place external sensors. PCB component count decreases when using a device that provides multiple inputs.Better temperature sensing improves product performance and reliability. Disk drive data integrity suffers at elevated temperatures. IBM published an article stating that a 5°C rise in operating temperature causes a 15% increase in the drive’s failure rate. The overall performance of a system can be improved by providing a more accurate temperature measurement of the most critical devices allowing them to run just a few degrees hotter.The LM83 directly senses its own temperature and the temperature of three external PN junctions. One is dedicated to the CPU of choice, the other two go to other parts of your system that need thermal monitoring such as the disk drive or graphics chip. The SMBus-compatible LM83 supports SMBus timeout and logic levels. The LM83 has two interrupt outputs; one for user-programmable limits and WATCHDOG capability (INT), the other is a Critical Temperature Alarm output (T_CRIT_A) for system power supply shutdown.

The AZ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current. The AZ1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V and adjustable versions or 2% for 1.2V version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. The AZ1117 has an adjustable version, that can provide the output voltage from 1.25V to 12V with only 2 external resistors.

This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar junction Transistor. Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant) Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)] Use Coupling Capacitors to separate the AC signals from the DC biasing voltage (which only pass AC signals and block any DC component). Use Bypass Capacitor to maintain the Q-point stability. To determine the value of each component, first set Q-point close to the center position of the load line. (RL is the resistance of the speaker.)
