模拟电子 新型精密运算放大器应用
Application considerations and circuits for the LT1001 and LT1002 single and dual precision amplifiers are illustrated in a number of circuits, including strain gauge signal conditioners, linearized platinum RTD circuits, an ultra precision dead zone circuit for motor servos and other examples.
无线通信 错误观念妨碍电量计在无线手机中的应用
Abstract: Most hand-held products lack accurate battery-charge monitors ("fuel gauges") because of the misconception that an accurate fuel gauge is difficult to achieve. This article debunks the myths and discusses how to accurately monitor charge at all temperatures, charge and discharge rates, and ...
