摘要

能量接收电路最主要的性能参数为功率转换率。为了提高电压转换率和功率转换率,通过对全向能量接收电路的理论分析,提出了使用低功耗高速比较器来控制mos管开关的方法。同时分析了闩锁效应,采用CMOS工艺设计了一种应用于胶囊内窥镜的高效全向能量接收电路。并用CSMC 0.5um工艺对该电路进行了仿真,仿真结果表明,该电路的电压转换效率可达97%,满足内窥镜对能量的要求。
        In the energy receiving circuit, power conversion rate is the main performance parameter. Based on the theoretical analysis of omnidirectional energy receiving circuit, the article puts forward a method which low-power and high-speed comparator controls the switch of the MOS transistors to improve the voltage and power conversion rate.Meanwhile, the article analysis the Latch-Up Effect and use the CMOS craft to design a kind of efficient omnidirectional energy receiving circuit for capsule endoscopy, and then the CSMC's 0.5 um is used to simulate the circle working. The simulation results show that the voltage conversion rate is up to 97% and can meet the requirements of endoscopy for energy.
