PCBA scheme

无论是模电还是数电，理论知识相对来说还是比较枯燥，各种电路原理理解清楚不算容易，换一种生动形象的方式或许会增加一些趣味性，也更容易理解这些知识。下面整理了一些常见的电路，以动态图形的方式展示。


整流电路

 

单相桥式整流电路

单相半波整流电路

全波整流电路

全波整流与半波整流对比

半波精密整流电路

半波整流波形分析

通过一个二极管实现半波整流。其中1kΩ的电阻是负载。半波整流电路，即把“交流电压”转变为“脉动直流电压“。所谓“脉动直流电压“，是指电压方向（正负极）不变，但大小随时间变化。各点波形如下：

The influence of temperature on the current mirror circuit This article tests the circuit stability of a current mirror composed of two discrete transistors. I never expected that the biggest factor affecting the output current would be the temperature of the transistor. If the temperature of the output transistor is high, the output current will increase. If the temperature of the reference current transistor increases, it will cause a decrease in output current. I really didn't expect the significant impact of this temperature on the circuit.
Dynamic diagram analysis of analog and digital electricity, understanding in seconds after reading Whether it is analog or digital, theoretical knowledge is relatively dull, and understanding various circuit principles is not easy. Changing to a vivid and vivid way may increase some fun and make it easier to understand these knowledge. Below are some common circuits presented in dynamic graphics.
