[Mo GE's daily dry goods, article 1] This title is a little white and must have thought: "Is it nonsense again ?! Title party ?!" Yesterday in a Shanghai it Startup Group, I gave a group of students a little analysis of his website. His website is youkoo.cn, and the Chinese name is aliku, which is used for IC search. In fact, the conversation is quite long. I want to buy food and cook for me, so I will simply write it. First of all, he thinks that the

Transistor Saturation Problem Summary:1. In practical work, the common ib*β=v/r is used as the condition for judging the critical saturation. According to the IB value calculated by IB*Β=V/R, only the transistor enters the initial saturation, in fact should take the value of more than a few times to achieve true saturation, the larger the multiplier, the deeper the saturation .2. The larger the collector resistance, the more easily saturated;3. Saturation zone phenomenon is: Two PN junction is p

Building a Django environment using the IBM Bluemix container Create a user First you need to create a user on the IBM bluemixTo create a successful user, you can access the IBM Bluemix Dashboardhttps://console.ng.bluemix.net/ Install cloudfoundry command line tool You can download the installation package from the link belowHttps://github.com/cloudfoundry/cli#downloadsHttps://cli.run.pivotal.io/stable?release=redhat64source=github For CentOS, use the second link, and then install the RPM pack

bias state when the point B potential is higher than the point B potential, the collector power EC is higher than the base power EBO.When manufacturing a transistor, consciously make the majority of carrier concentrations in the emission zone greater than the base zone, while the base zone is very thin, and strictly control the impurity content, so that once the power is connected, due to the correct launch knot, the majority of carriers (electrons) in the launch zone and the majority of carrie

InThis article explains how to create and compile GTK under the Windows operating system. GTK uses glib, Cairo, pango, ATK, GTK +, and gettext-Runtime, LibPNG, libjpeg, LibTIFF, and zlib. Therefore, you must also obtain these kits, which can be obtained from Windows download on the GTK official website, the simplest way is to get all-in-one bundle. The following describes the steps for security protection: Renew minggw in http://www.mingw.org/ Obtained from GTK Official WebsiteAll-in-One bund

Read Card processingFor POS terminals that support IC card transactions, if the cardholder is using a magnetic stripe card with a chip, the operator should first attempt to trade using an IC card.For a POS terminal that supports EMV transactions, when the magnetic stripe of the card is

Currently, the charging management IC on the market is designed based on the charging characteristics of the rechargeable battery. Rechargeable Batteries are divided into Ni-MH batteries and lithium batteries based on different charging media. Because the lithium battery has no memory effect, lithium battery is currently used in various handheld devices and portable electronic products. Due to the charging characteristics of lithium battery. The charg

transistor. (as in push-pull) when the bottom transistor is off, the output is high. There is no way to output a high level, you want to output a high level, must be externally connected with a pull-up resistor (pull-up resistor). The Open-drain is only capable of leakage currents (sink current), and a pull-up resistor is required if you want to set the current. Out low level common Gpio mode can be configured as Open-drain or Push-pull, specifically implemented, It i
