摘要
负电压发生器,具有可靠性及实用性,解决了运算放大器供电问题,利用CPU内部资源结构简单的特点,采用负电压发生器来为运算放大器提供负电源,利用HT46R47单片机和一片运放大器TL062来完成整机主要功能,表述了各部份电路实现与调试方法.
Negative voltage generator is very reliable and practicable, and can solve the problem to supply power for operational amplifier. Operational amplifier supplies negative power by negative voltage generator, which makes use of the characteristic of simple structure of CPU internal resource. The major function of the complete machines was implemented by SCM HT46R47 and Operational amplifier TL062. How to implement each part of circuit and how to debug are described in the paper.
