Circuit Design: This is a very big concept, from the voltage intensity can be divided into strong electric circuit design and Weak Current Circuit Design; from the design tool can be divided into manual drawing and electronic auxiliary design, the circuit types can be divided into analog circuit design and digital circuit design. Icdesign: The IC Design refers to the chip design, that is, the design of the circuit on a crystalline silicon chip, whi

Relative humidity measurement using IC SensorsXie Changjiang youlihuaSummary: Based on the comparison of various relative humidity measurement methods and sensors, this paper introduces the characteristics and usage of integrated humidity sensor based on examples, and points out the influencing factors and compensation methods of the conditions, the specific implementation line of relative humidity detection with temperature effect compensation is pro

In the BS structure of the program, how to develop a cross-web browser IC card reader program?In general, the use of physical hardware in a BS structure program has many limitations, and the OCX control that is addressed through ActiveX technology is only available on IE and cannot be used in Chrome or Firefox. Friends of my technology to provide RFID reader cloud services to completely solve this problem, he can not only use in IE, but also in the Ch

AbstractThe attacker of μClinux does not need to upload the program on de2. The important thing is how to place our program on μClinux to upload the program. IntroductionOn de2, how does one install the μClinux operating system? In (IC design) (de2) (nioii) (OS) (Linux) (μClinux), we have run μClinux on de2, is this the end? Developers are concerned about how to run their own programs on μClinux. There are two problems to solve:1. How to Use the n

Linear Technology ' s recently introduced LTC4300 chip buffers i²c clock and data lines to and from a hot-swappable card. This task was difficult because the IC must work bidirectionally, meaning so can simultaneously and actively drive BO Th sides. However, as is sometimes the case, you can replace a complicated circuit by a simple one without much loss of performance. For example, transistors and resistors replace the entire

Generally, the temperature levels of common IC are represented by C (commercial level) and I (industrial level), which are usually given in the suffix of IC. The following uses Maxim's max696cwe as an example to illustrate (different brands and different types of chips are represented in different ways. Here, we will only make a reference ):Max696cweC = the operating temperature range is commercial grade (0

For everyone to make a simple integrated IC, in fact, always want to do this stuff, because from a small time often contact with the electronic category of things. When making the main use of pen tools and gradient tools to render the texture of the IC can be. We can also find some kind of drawing for reference when we make the effect picture, which will help us a lot.Final effect

technology is also the effect of radio wave communication and electromagnetic. As for the application of embedded on-chip systems, the key lies in the understanding of chips, but it was not clear at the time, but with curiosity and interest. I heard that a company next to the school did a great job in this area, so I volunteered to call the internship in the summer of my junior year. From then on, I was exposed to smart IC cards and mobile payments
