In modern times, mobile devices have become very popular, because of the ease of use even outside the room though. Its simplicity to carry anywhere, of course, making mobile devices requires a source of electricity from the battery. The use of a battery is indeed the best solution, but the battery has limitations in providing electricity. For this reason, we need another device that can charge the battery anywhere and anytime. For this reason, a power bank was created to charge mobile devices everywhere. Basically the power bank is an electronic device consisting of a lithium-ion battery and a DC to DC boost converter circuit, which is able to change the voltage of 3.7 volts from the battery to 5 volts DC. DC to DC boost converter system Works with the high frequency switching method so that it is quite efficient in consuming battery power. The DC to DC boost converter consists of main components such as ferrite core inductors, mosfets, ultrafast diodes and filter capacitors. Electri...

DC boost converter technology or DC to DC step up converter, is one of the most widely used systems in modern electronic devices. DC boost converter allows the power supply unit to be made as simple as possible, because the power supply unit has only one output channel. In this way, electronic devices can be made more concise. Examples of the use of the easiest to find include, the use of a DC boost converter circuit on LED televisions and LED monitors. Modern LED tv mainboards are very compact, because they only use a power supply circuit with one output channel. To provide sufficient power to the LED backlight unit, a DC boost converter system is used which is able to change the 12 volt DC voltage from the power supply unit to 32 volts or more. Meanwhile, to meet the needs of the main processor power used a DC buck converter circuit which is able to reduce the 12 volt DC voltage to 5 volts DC efficiently. One of the main reasons for using a DC boost converter is that it has very go...

Mungkin banyak dari kita yang yang belum tahu apa itu Gallium Nitride. Gallium nitride adalah material semikonduktor bandgap langsung biner III / V yang cocok untuk aplikasi transistor daya tinggi yang mampu beroperasi pada rentang suhu yang  jauh lebih tinggi dari transistor silikon biasa.  Sejak era 1990-an, Gallium nitride telah digunakan secara khusus dalam dioda pemancar cahaya atau (LED). Gallium nitride mengeluarkan cahaya berwarna biru yang digunakan untuk membaca disk dalam Blu-ray. Selain itu, gallium nitride juga digunakan dalam perangkat daya semikonduktor, seperti komponen RF, laser, dan fotonik. Silicone wafer Pada tahun 2006, transistor GaN peningkatan-mode, lebih dikenal sebagai FET GaN, transistor ini mulai diproduksi dengan menumbuhkan lapisan tipis GaN pada lapisan AIN dari sebuah wafer silikon standar menggunakan deposisi uap kimia logam organik (MOCVD). Lapisan A.I.N ini bertindak sebagai penyangga antara media dan GaN. Pros...

FM radio is an FM broadcast radio receiver (frequency modulation) that has the advantage of being able to transmit broadcasts in stereo format. despite having the advantage of sending stereo broadcasts, FM waves have a relatively short range. many electronic hobbyists want to make their own radio fm, but many circuit schemes use ic fm, and this is considered less challenging. Simple FM receiver circuit diagram the fm radio circuit scheme consisting of several transistors is a circuit scheme that is sought, because it is easier to understand how it works. this time I will share the fm radio circuit scheme consisting of several transistors.  some parts of the scheme of the FM receiver radio circuit use transistors, such as the RF amplifier, tuning, and if amplifier parts. with the use of transistors in the FM radio circuit scheme, this series can be used for learning materials about how a FM radio receiver works.

At present the world of aviation has been very advanced, this is evidenced by the rapid intercontinental flights, and accompanied by increasingly cheaper costs. All of this can be realized with the use of super materials, in the constituent components of an aircraft. To reduce flight costs, one way that can be applied is by reducing the weight of aircraft. In this way the aircraft fuel consumption becomes more efficient, so the cost of flights will be cheaper. To reduce the weight of an aircraft, for now using lightweight and strong carbon fiber and aluminum alloy materials. This material is very strong and has a light weight, so it can be used to make aircraft parts. In addition to the development of the fuselage, the scientists also developed another important part of the engine. As we all know airplane can take off, and fly because it gets thrust from a jet engine. Jet engines are one of the strongest engines on earth besides Rocket engines. The jet engine is ab...

FM receiver or FM radio is the most popular radio receiver for now. Its advantages, among others, can be used to transmit broadcasts with stereo format. So the music show on FM radio has better sound quality than AM radio. Many of the analogue electronics hobbyists consider that to make an FM receiver quite difficult. Because, many of the FM radio circulating using ic receiver so this makes us think it will be difficult to make it simpler.  For this time I will share the FM receiver scheme from the electronic kit of the 90s, and the receiver scheme is quite easy to make because it uses only some electronic components only. Simple FM receiver circuit diagram Basically this receiver scheme is a rf circuit amplifier, oscillator, and audio amplifier made very simple. Hopefully this FM  receiver scheme can help you with your FM receiver project. Simple FM receiver circuit diagram Simple FM receiver circuit diagram
