'> I would like to ask about the current status of integrated circuits, and I hope that professionals will give you an overview of...
1, Integrated circuit is an important part of the development of science and technology in China, but also the basis for all walks of life to achieve intelligence and digitalization. At present, China's integrated circuit penetrates into various industries in China, such as industrial robots, 5G network construction, automotive electronics and computers and other important scientific and technological fields, it can be said that integrated circuit is the cornerstone of China's scientific and technological development, integrated circuit technology development in place, China can lead in science and technologyDomain is not subject to others.
2, the design of integrated circuits, I personally suggest that you can rely on this aspect of communication, because the final circuit is inseparable from computer programming. As things stand, jobs are relatively easy to find. And to Nanjing, Shanghai and other places of work is also relatively easy to find, the salary can also be generally 7K upward.
3, connect the battery only need to connect the red line on the light to the positive electrode of the battery and the black line to the negative electrode on the line, go to the hardware to buy two small battery clips connected to the line when the battery clips on the line. No voltage stabilizer is needed at all. I hope it helps. <4, the magnification in the second picture is less than 200 (21/0.01=121), but did you consider adjusting the potentiometer to the maximum input? Because the magnification of the amplifier refers to the output voltage of pin 5 / input voltage of pin 3 of the integrated circuit.
5, your power supply is 5V 4A, that is a 20W power supply. This power supply, generally using flyback topology, you also explained that your power supply has a PWM chip (let's consider it PWM, it may be other ways, but PWM at most) and power MOS, feedback 817 431.
1, Pu Cheng. The National Timing Center is located in the west of Pucheng county, Shaanxi province, with four 200-meter-tall iron towers rising into the sky, as well as a spectacular array of antennas and launch rooms, which have been garrisons of the People's Liberation Army, and later an armed police squadron. For a long time, the surrounding people know that this is a confidential unit, there is a code name "326". After the 1980s, this Chinese timepiece was gradually known.
2, its headquarters is located in the westAn Lintong, and the timing department is located in Pucheng. The origin of the timing work can be traced back to the Purple Mountain Observatory. In 1955, due to the needs of national defense, the timing platform was planned to be established in the northwest region, and the final site was located in Yangling Town, Wugong County.
3. National Timing Center of Chinese Academy of Sciences is located in Pucheng County, Weinan City, Shaanxi Province. The National Timing Center of the Chinese Academy of Sciences, formerly known as Shaanxi Astronomical Observatory, is a comprehensive astronomical research institution focusing on time and frequency research and timing services, and also carrying out astrometry, heliophysics, Sun-earth relations, celestial mechanics, satellite observation and research. The whole Taiwan is divided into two parts: the Taiwan headquarters and the Timing department.
