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.

分而治之方法還可以用于實現另一種完全不同的排序方法，這種排序法稱為快速排序（quick sort）。在這種方法中， n 個元素被分成三段（組）：左段l e f t，右段r i g h t和中段m i d d l e。中段僅包含一個元素。左段中各元素都小于等于中段元素，右段中各元素都大于等于中段元素。因此l e f t和r i g h t中的元素可以獨立排序，并且不必對l e f t和r i g h t的排序結果進行合并。m i d d l e中的元素被稱為支點( p i v o t )。圖1 4 - 9中給出了快速排序的偽代碼
