模拟电子 降低EMI和保持高效率D类放大器在便携式产品中的应用
Abstract: Class D amplifiers are typically very efficient, making them ideal candidates for portable applications that require longbattery life and low thermal dissipation. However, electromagnetic interference (EMI) is an issue that commonly accompanies theClass D switching topology. Active-emiss ...
模拟电子 二极管导通开关稳压器引发的故障时间
 
Most circuit designers are familiar with diode dynamiccharacteristics such as charge storage, voltage dependentcapacitance and reverse recovery time. Less commonlyacknowledged and manufacturer specifi ed is diode forwardturn-on time. This parameter describes the timerequired for a diode t ...
电源技术 LTC1325电池管理IC的使用
 
For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-s ...
单片机编程 STM32，5110液晶显示超声波测距探鱼器200KHz，带电路图，精确到厘米
STM32，5110液晶显示声纳探鱼器200KHz，带电路图，精确到厘米 MC34063升压，大声压发射，实际板子上滤波电路没要（电路图上的滤波电阻电容电感没焊，开路或者短路）。一般200KHz的换能器在水里面的耦合比较好，在空气中发射出来的（或者接收的）强度很低。 用的MOSFET Relay，contact和release时间都可以做到很小，不过选的 ...
通信网络 WP150-解决数兆兆位及更高的网络挑战
 
In today’s world of modular networking and telecommunications design, it is becomingincreasingly difficult to keep alignment with the many different and often changing interfaces,both inter-board and intra-board. Each manufacturer has their own spin on the way in whichdevices are co ...
无线通信 差分電路中單端及混合模式S-參數的使用
Single-Ended and Differential S-Parameters
Differential circuits have been important incommunication systems for many years. In the past,differential communication circuits operated at lowfrequencies, where they could be designed andanalyzed using lumped-element models andtechniques. With the freque ...
数据结构 The government of a small but important country has decided that the alphabet needs to be streamline
The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B ...
