Problem description:For most chips, there is usually a soft start pin in the chip's function pins. Its function is to slowly increase the output voltage to the set value and reduce the inrush at the s
1. I recently encountered this problem when adjusting the board: the board functions normally when the emulator is plugged in and running online, but some functions of the board are abnormal when it i
We often come into contact with crystal triodes and are familiar with their use. Relatively speaking, we are a little unfamiliar with crystal field effect tubes. However, due to the unique advantages
1. High frequency resistor
The most common circuit element in low-frequency electronics is the resistor, which is used to reduce voltage by converting some electrical energy into heat. The high-freque
