Embedded Files
Currently I am working on embedded System design as an entrepreneur. I dream to design various microelectronic and power electronic devices which will dominate the market place in Bangladesh as well as aboard. My main goal is to gather knowledge and implement it for the better life of mankind. I always dream to build an electronic design company where a lot of engineers will work and build our universe better place. For this reason, I always try to build up theoretical knowledge first. Time is limited but There is a lot of things pending to do.

VLSI DESIGN
VLSI DESIGN
It's really amazing that human being can design and fabricate such kind of small object that can't be seen as they are too small. All the complex device that you are using today or tomorrow is the blessing of VLSI. Very large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions of MOS transistors onto a single chip. The microprocessor and memory chips are VLSI devices. Before the introduction of VLSI technology, most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other logic. VLSI enables IC designers to add all of these into one chip called system on chip.
POWER ELECTRONIC
POWER ELECTRONIC
Now a days, every industrial machine is controlled by power electronic devices. So there is a huge market for designing efficient controller. Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with semiconductor switching devices such as diodes, thyristors, and power transistors such as the power MOSFET and IGBT. It starts from ten watts and ends at tens of megawatts. The power conversion systems can be classified according to the type of the input and output power: AC to DC (rectifier) DC to AC (inverter) DC to DC (Buck–Boost) AC to AC (Cycloconverter)

My focus is to design the controller of alternator which can be operated parallelly with large power system. Currently BANGLADESH import it from foreign country. For this reason i want to design it in BD. An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.
MICROWAVE
MICROWAVE
The most interesting thing that i found in my life is microwave signal. you can't see the signal but can apply all complex mathematical equation. Again you can't see the magnetic or electric field but combining field can be visible light that help you to see all the object in the world. Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. A more common definition in radio-frequency engineering is the range between 1 and 100 GHz (wavelengths between 0.3 m and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.
