It is well-known that the CML or SCL DFFs can achieve high-speed divide-by-2 function. The figure attached shows a simple CML DFF. Different kind of bias for the CML is popular. 1. No current tail is utilized; 2. M3,4 and M5,6 are biased by different currrent tail I1 and I2, respectively; 3. The sampling transistor M3,4 and M5,6 share the same current tail.

Two simple DFF cell can achi...

Many are predicting death of Ultra Wideband technology in consumer and computer markets. Since 802.11 (Wi-Fi) is approaching 1GB/s speed standard and emergence of 60GHz wireless standard, UWB solutions have limited market share. How come many UWB companies have folded in recent time namely WiQuest, Tzero, Radiospire and even WiMedia Alliance. Some other UWB Companies have found other ways to sur...
