摘要

介绍了一种用于无线胶囊内窥镜的432 MHz功率放大器。采用180nm CMOS工艺，电源电压1.8 V。为了满足高效率的要求，选择了d类。根据布局后的蒙特卡罗模拟，PA在提供3 dBm输出功率的同时实现了60%的功率效率。因此，这项工作表明，d类拓扑可以用于胶囊内窥镜，在胶囊在胃肠道中推进的同时，以显著的效率提供最大的输出功率，并延长电池寿命。

A 432 MHz Class-D Power Amplifier with 60% Power Efficiency for Wireless Capsule Endoscopy

A 432 MHz power amplifier (PA) for wireless capsule endoscopy is presented. 180 nm CMOS process is used with a 1.8 V supply voltage. Class-D is chosen in order to meet the high-efficiency requirement. According to the post-layout Monte Carlo simulations, the PA achieves 60% power efficiency while delivering 3 dBm output power. Hence, this work demonstrates that the class-D topology can be employed in capsule endoscopes to deliver a maximized output power with significant efficiency and extend the battery life while the capsule advances in the gastrointestinal tract.
