资料介绍
针对兆赫兹级高频SAW电子烟雾化芯片驱动需求,基于单片机控制及直接数字频率合成技术,设计开发了一款由单片机控制模块、信号发生模块、信号处理模块、人机交互模块和电源模块构成的驱动控制电路,搭建了测试系统,并对电路的工作性能进行了测试分析。结果表明,该电路可实现0~65 MHz的高频信号输出、频率误差小,且输出功率可达4.5 W,是一款信号输出稳定可靠、精度高、频率可调范围广、负载驱动能力强、小巧便携的驱动控制电路。本文的工作对于加速SAW技术在电子烟烟油雾化方面的应用具有重要参考价值,同时也可拓展应用于其他SAW微流体雾化驱动领域。
In order to meet the requirements of MHz high frequency driving in SAW( surface acoustic wave)-electronic cigarette atomization chip, a novel driving and controlling circuit has been designed and developed based on MCU control and DDS( direct digital frequency synthesis) technology, which is composed of MCU control module, signal generation module, signal processing module, human-machine interaction module, and power supply module. The systematic test platform has been setup, and the working performance of the driving and controlling circuit has been tested and analyzed. The results show that the circuit can realize sinu-soidal signal output with high frequency from 0 MHz to 65 MHz, small frequency error( ~ 0. 02 %-1. 9 %), and adjustable power up to 4. 5 W. Further, the circuit also shows significant performances with stable and reliable signal output, high precision, wide frequency range, and strong load driving capability. The work of this paper will potentially drive the application of SAW technology in the atomization of E-liquid, and the circuit can also be extended to be applied in other fields in SAW-microfluid atomization.
