The flood disaster in Henan has not ended yet, and the epidemic has broken out again in various places. It has been a year of disasters. But recently I saw China win the Olympic Games. We won four gol...
At present, 8Vpp and pulse width modulated RF high voltage/high power drivers can be realized based on 1.2V 65nm CMOS technology. In the operating frequency range of 0.9 to 3.6GHz, the chip can provi...[Details]
There are two projects in hand. When the user is not operating, the system must enter low power mode. The two projects use STM8L101 and STM8L151 respectively. The system running clock of both projects...[Details]
As mentioned in the previous section, the 4th and 5th bits of the control word are used to control whether the analog input pin of PCF8591 is single-ended input or differential input. Differential in...[Details]
Introduction The switching power supply is a new type of regulated power supply that uses modern power electronics technology to control the turn-on and turn-off time ratio of the power switch tub...[Details]
Preface The 10x passive probe is our most commonly used probe. Almost every oscilloscope is equipped with this probe as standard. However, even so, there are still many misunderstandings in our under...[Details]
Long-term poor posture can cause pain and discomfort, and increase the risk of cardiovascular disease, vision problems, stroke, and musculoskeletal disorders. To avoid these problems and improve the ...[Details]
The basic 51 microcontroller has four parallel ports, which also includes a serial port. When there are not enough interfaces, people will think of using external chips for expansion. However, al...[Details]
