主要介绍了高效率E类射频功率振荡器的原理和设计方法，通过电路等效变换，E类射频功率振荡器最终转换成与E类放大器相同的结构，MOS管工作在软开关状态，漏极高电压、大电流不会同时交叠，大大降低了功率损耗，在同等工作条件下，能够获得与E类放大器相似的高效率。文中以ARF461型LDMOS做为功率器件，结合E类射频振荡器在等 ...

Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry ca ...

This is the second half of our Transistor Circuits e-book. It contains a further 100 circuits, with many of them containing one or more Integrated Circuits (ICs).It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded.

当许多编程人员从事这项工作但又不使用源代码管理工具时，源代码管理几乎不可能进行。Visual SourceSafe是Visual Basic的企业版配备的一个工具，不过这个工具目的是为了保留一个内部应用版本，不向公众发布（应当说明的是，M i c r o s o f t并没有开发Visual SourceSafe，它是M i c r o s o f t公司买来的） 。虽然Visual ...

2.1.2 SPARTANⅡ和SPARTANⅡE系列产品

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development e ...

Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wir ...
