Abstract

EDGE is currently the most widely used standard for data communications in mobile phones. Its proliferation has led to a need for low-cost 2.5G mobile solutions. The implementation of RF circuits in nanoscale digital CMOS with no or minimal process enhancements is one of the key obstacles limiting the complete SoC integration of cellular radio functionality with digital baseband. The key challenges for such RF integration include non-linearity of devices and circuits, device mismatches, process parameter spread, and the increasing potential for self-interference that could be induced by one function in the SoC onto another.
一个0.8mm2全数字无锯极性发射器在65nm EDGE SoC
EDGE是目前应用最广泛的移动电话数据通信标准。它的扩散导致了对低成本2.5G移动解决方案的需求。在纳米级数字CMOS中实现射频电路,没有或只有很少的工艺增强,这是限制蜂窝无线电功能与数字基带完全集成的主要障碍之一。这种射频集成的关键挑战包括器件和电路的非线性、器件不匹配、工艺参数扩散,以及SoC中一个功能对另一个功能可能引起的自干扰的潜在增加。
