RF components and RF chips are the core of wireless connections and an important part of the semiconductor industry. With the advent of 5G and WIFI6, RF technology has also encountered new challenges
Recently, I have read the libraries of TI and STM32. Regarding the sensorless part of permanent magnet synchronous motor, there is no open source for the position and angle estimation algorithm, and I
I recently took a professional exam and there was a set of questions like this: What are synchronous circuits and asynchronous circuits?What are the rectification and boosting methods you know? What a
The flyback power supply has a sound problem when the load is small
The main control is UC3842, the power supply can work normally, the output of pin 1 is normal when under load, there is a sound when
