To ensure reliable operation of the chip, these companies need to test the FLASH memory at high speed and meticulously before the product to the market. Therefore, it is very necessary to have FLASH memory tests.

A resistor works by restricting the flow of current, it can do this in one of three ways: firstly, by using a less conductive material, secondly by making the conductive material thinner and finally by making the conductive material longer. So how does resistor work in transistor

As we all know, diodes are drawn on schematics by a standard symbol below that shows how the diode should be installed in circuits. However, do you know that different diodes have different symbols. Here introduces common diodes symbols with short words details about them. A d...

IntroductionIn modern daily life, you can always see one or more USB ports on virtually desktop computers, laptops, TVs, game system devices, cars, media players, and other devices, etc. USB devices are very common, in addition, we probably know what it used for. However, fewe...

Introduction People live in an analog world, however, we are surrounded by digital devices. Light, temperature, speed, pressure, sound etc, they are analog signals. If you want to use them, how do you convert analog signal to digital signal? Here we introduce a device Analog-t...

IntroductionAn operational amplifier or op-amp is used in a wide variety of applications in electronics. It generally comprises a differential-input stage with high input impedance, an intermediate-gain stage, and a push-pull output stage with a low output impedance. Common op...
