I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]
My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
