A large BODY of computer-aided techniques has been developed in recent years to assist in the process of modeling, analyzing, and designing communication systems . These computer-aided techniques fall into two categories: formula-based approaches, where the computer is used to evaluate complex formulas, and simulation-based approaches, where the computer is used to simulate the waveforms or signals that flow through the system. The second approach, which involves “waveform”-level simulation (and often incorporates analytical techniques), is the subject of this book. Since performance evaluation and trade off studies are the central issues in the analysis and design of communication systems, we will focus on the use of simulation for evaluating the performance of analog and digital communication systems with the emphasis on digitalcommunication systems.

The past decades have witnessed wide demand and applications for wireless commu- nications in the human BODY area, that is, in the immediate environment around a human BODY. These demands and applications especially focus on wireless transmis- sion and networking of personal information for user identification, healthcare and medical applications.

對于常規VDMOS器件結構, Rdson與BV存在矛盾關系,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增大。所以對于普通VDMOS,兩者矛盾不可調和。 但是對于COOLMOS,這個矛盾就不那么明顯了。通過設置一個深入EPI的的P區,大大提高了BV,同時對Rdson上不產生影響。為什么有了這個深入襯底的P區,就能大大提高耐壓呢? 對于常規VDMOS,反向耐壓,主要靠的是N型EPI與BODY區界面的PN結,對于一個PN結,耐壓時主要靠的是耗盡區承受,耗盡區內的電場大小、耗盡區擴展的寬度的面積,也就是下圖中的淺綠色部分,就是承受電壓的大小。常規VDMOS,P BODY濃度要大于N EPI, PN結耗盡區主要向低參雜一側擴散,所以此結構下,P BODY區域一側,耗盡區擴展很小,基本對承壓沒有多大貢獻,承壓主要是P BODY--N EPI在N型的一側區域,這個區域的電場強度是逐漸變化的,越是靠近PN結面(a圖的A結),電場強度E越大。所以形成的淺綠色面積有呈現梯形。

Occasionally, we are tasked with designing circuitry for aspecific purpose. The request may have customer originsor it may be an in-house requirement. Alternately, a circuitmay be developed because its possibility is simply tooattractive to ignore1. Over time, these circuits accumulate,encompassing a wide and useful BODY of proven capabilities.They also represent substantial effort. These considerationsmake publication an almost obligatory propositionand, as such, a group of circuits is presented here. This isnot the first time we have displayed such wares and, giventhe encouraging reader response, it will not be the last2.Eighteen circuits are included in this latest effort, roughlyarranged in the categories given in this publication’s title.They appear at the next paragraph.

This application report discusses the design of non-invasive optical plethysmographyalso called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). Thepulsoximeter consists of a peripheral probe combined with the MCU displaying theoxygen saturation and pulse rate on a LCD glass. The same sensor is used for bothheart-rate detection and pulsoximetering in this application. The probe is placed on aperipheral point of the BODY such as a finger tip, ear lobe or the nose. The probeincludes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) andthe other in the infrared spectrum (940nm). The percentage of oxygen in the BODY isworked by measuring the intensity from each frequency of light after it transmitsthrough the BODY and then calculating the ratio between these two intensities.
