摘要
连接蜂窝设备数量的爆炸式增长和不断增加的数据带宽需求最近推动了对射频功率放大器(pa)的需求，这需要pa覆盖比以往更多的频段。这个问题的一个潜在解决方案是使用可调匹配网络(TMN)。本文提出了一种基于0.18 μm SOI CMOS技术的TMN，主要研究了阻抗覆盖和功率传输。该设计采用特殊的浮体晶体管作为开关元件，实现电容器和电感阵列的开关。
A tunable matching network for TD-SCDMA power amplifier in 0.18-μm SOI CMOS technology
The explosion in the number of connected cellular devices and ever-increasing data bandwidth requirements have recently fueled the demand for RF Power Amplifiers (PAs) which needs PAs to cover more bands than ever before. A potential solution to this problem is by the use of Tunable Matching Networks (TMN). In this paper, we present a TMN fabricated under 0.18-μm SOI CMOS technology, focusing mainly in the impedance coverage and the power transmission. The design employs special floating body transistors as switching components to turn on and off the capacitors and the inductor array.
