消除测试设备对器件测量影响

提高精度已成为最早期矢量网络分析仪（VNA）测量的目标。通过校准和矢量误差校正技术，可以将VNA精度从仪器端口扩展到测试电缆的端点。当待测器件（DUT）直接连接到测试端口电缆时，校准面和测量面是同一平面。在这种情况下，校准和误差校正是直截了当的过程，其涉及机械或电子同轴校准标准。然而，对引脚贴装或表面贴装封装的DUT而言，必须使用测试设备，而目前同轴校准平面和测量平面是分开的，并需要额外的误差校...[详细]

基于ARM7内核LPC2119芯片实现双向变换器的设计

在这些应用当中，很多时候都要求开关电源不仅能够控制能量的双向流动，还要能够实现低压、大电流的输出。在开关频率不太高的情况下，随着输出电压的降低、输出电流的增加，整流损耗就成了影响开关电源效率的主要冈素。因此，为了提高开关电源的效率，就必须设法降低整流损耗。而在本文中采用的同步整流技术就是一种降低整流损耗的有效手段。在以往的电源设计当中，模拟控制技术因其动态响应快、无量化误差、价格低廉等优点...[详细]
