Thanks to eeworld, I am very happy to get the "trial voucher" of "Operational Amplifier Parameter Analysis and LTspice Application Simulation". In fact, I had my own purpose in applying for this book....
To introduce the push-pull circuit, we first introduce some basic knowledge of power amplifiers. From the perspective of energy control, there is no essential difference between power amplifier circui...
I want to learn high-speed PCB wiring. The first problem I encountered is how to place vias. For example, how big should the vias be for 8mil and 6mil lines? What should I pay attention to when crossi...
Function full name: 50us delay Notes: Based on 1MIPS, AT89 series corresponds to 12M crystal oscillator, W77, W78 series correspond to 3M crystal oscillator Example Tips: Call delay_50us(20) to get 1m...
