Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total output signal swing. Since many lowvoltageapplications are single-ended, the questions arise,“How can I use a differential I/O amplifi er in a single-endedapplication?” and “What are the implications of suchuse?” This Design Note addresses some of the practicalimplications and demonstrates specifi c single-endedapplications using the 3GHz gain-bandwidth LTC6406differential I/O amplifi er.
當今電子系統如高端處理器及記憶體，對電源的需求是趨向更低電壓、更高電流的應用。同時、對負載的反應速度也要提高。因此功率系統工程師要面對的挑戰，是要設計出符合系統要求的細小、價廉但高效率的電源系統。而這些要求都不是傳統功率架構能夠完全滿足的。Vicor提出的分比功率架構(Factorized Power Architecture FPA)以及一系列的整合功率元件，可提供革命性的功率轉換方案，應付以上提及的各項挑戰。這些功率元件稱為V•I晶片。
