1. Transistor
The transistor is a current-controlled device. Its main function is to amplify weak signals. It has low input impedance. For example, a very small current Ib is given to the base b, an...
There are generally two ways to increase the transmission rate of wireless transmission. One is to increase the spectrum utilization rate, and the other is to increase the spectrum bandwidth. In wirel...

1. Background
I have done a project on STM32 low-power signal acquisition before, using the STM32L031 microcontroller. The project requirements are as follows:
The device is powered by a battery, dete...
This article mainly introduces the design and analysis of a new bidirectional DC-DC converter. This new topology and its control strategy completely solve the voltage spike problem existing in traditi...
I learned a sensor circuit and thought it was well designed and interesting, so I analyzed it and recorded it. If there are any mistakes, please feel free to give me your advice. This circuit uses a 4...
