Dear Reader, this book project brings to you a unique study tool for ESD protection solutions used in analog-integrated circuit (IC) design. Quick-start learning is combined with in-depth understanding for the whole spectrum of cross- disciplinary knowledge required to excel in the ESD field. The chapters cover technical material from elementary semiconductor structure and device levels up to complex analog circuit design examples and case studies.

In the present era, low observability is one of the critical requirements in aerospace sector, especially related to defense. The stealth technology essentially relates to shaping and usage of radar absorbing materials (RAM) or radar absorbing struc- tures (RAS). The performance of such radar cross section (RCS) reduction tech- niques is limited by the bandwidth constraints, payload requirements, and other structural issues. Moreover, with advancement of materials science, the structure geometry no longer remains key decisive factor toward stealth.

Sensors are points ofcontact betweenthe material world ofatoms, mass, andenergy and the seemingly immaterial world of information, computation, and cognition. Linking these two domains more tightly yields all sorts of practical benefits, such as improvedinputdevicesforcomputers,moreeffectivemedicaldevices(implantedor worn), more precise agricultural operations, better monitored buildings or bridges, more secure payment systems, and more reliable sensor–actuator control systems. There are many settings in which tighter coupling between digital and physical planes can enhance safety, security, performance, and reliability.

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.)

ABSTRACTThe flyback power stage is a popular choice for single and multiple output dc-to-dc converters at powerlevels of 150 Watts or less. Without the output inductor required in buck derived topologies, such as theforward or push-pull converter, the component count and cost are reduced. This application note will reviewthe design procedure for the power stage and control electronics of a flyback converter. In these isolatedconverters, the error signal from the secondary still needs to cross the isolation boundary to achieveregulation. By using the UC3965 Precision Reference with Low Offset Error Amplifier on the secondaryside to drive an optocoupler and the UCC3809 Economy Primary Side Controller on the primary side, asimple and low cost 50 Watt isolated power supply is realized.

USB Power Delivery 快速充电通信原理本篇文章讲的快速充电是指USB 论坛所发布的USB Power Delivery 快速充电规范(通过VBUS 直流电平上耦合FSK 信号来请求充电器调整输出电压和电流的过程)，不同于本人发布的另一篇文章所讲的高通Quick Charger 2.0 规范，因为高通QC2.0是利用D+ 和D- 上的不同的直流电压来请求充电器动态调整输出电压和电流实现快速充电的过程。USB PD 的通信是将协议层的消息调制成24MHZ 的FSK 信号并耦合到VBUS上或者从VBUS 上获得FSK 信号来实现手机和充电器通信的过程。如图所示， 在USB PD 通信中， 是将24MHz 的FSK 通过cAC-Coupling 耦合电容耦合到VBUS 上的直流电平上的， 而为了使24MHz 的FSK 不对Power Supply或者USB Host 的VBUS 直流电压产生影响，在回路中同时添加了zIsolation 电感组成的低通滤波器过滤掉FSK 信号。
