模拟电子 模拟IC性能的权衡 模拟到数字化设计的挑战
Abstract: Many digital devices incorporate analog circuits. For instance, microprocessors, applicationspecificintegrated circuits (ASICs), and field-programmable gate arrays (FPGAs) may have internalvoltage references, analog-to-digital converters (ADCs) or digital-to-analog converters (DACs). How ...
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 ...
