基于C8051F410的精确信号模拟电路设计

The Design of Precise Signal Generator Circuit based on C8051F410

针对某型检测设备使用中存在的工作点不稳定问题,基于C8051F410单片机,采用PWM调制技术和负反馈测量技术设计了一种新型的精确信号模拟电路,有效抑制了工作点漂移问题,提高了模拟电路输出精度和抗噪性能。本电路的设计思想和方法对于同类电路的设计具有一定的借鉴意义。

Due to the problem that a certain test equipment could not work steadily, a new Precise Signal Generator Circuit is discussed. The new Circuit is based on C8051F410 SCM, Pulse-Width Modulation technology and Feedback Measurement. The new Circuit effectively restrains the instability, improve the precision and anti-jamming ability. The design idea and method of this Circuit can be used for reference by other Circuit designers.
