The main aim of this project is to design a 2 to 4 line Decoder

... A decoder is a combinational circuit with n inputs and at most 2n outputs. Its characteristic property is that for every combination of input values only one output will be equal to 1 at the same time. Decoder has a wide variety of applications in digital technology. They may be used to route input ...

... Unfortunately the 9050 RDK is no longer sold; it has been replaced by the 9052 RDK. The 9052 chip is supposedly compatible with the 9050, but the development board does not contain the socket into which the PLX daughtercard is plugged. A solution to using the 9052 has been investigated and it might ...

Power MOSFET



A power MOSFET is a specific type of metal oxide semiconductor field-effect transistor (MOSFET) designed to handle significant power levels.Compared to the other power semiconductor devices, for example an insulated-gate bipolar transistor (IGBT) or a thyristor, its main advantages are high commutation speed and good efficiency at low voltages. It shares with the IGBT an isolated gate that makes it easy to drive. They can be subject to low gain, sometimes to degree that the gate voltage needs to be higher than the voltage under control.The design of power MOSFETs was made possible by the evolution of CMOS technology, developed for manufacturing integrated circuits in the late 1970s. The power MOSFET shares its operating principle with its low-power counterpart, the lateral MOSFET.The power MOSFET is the most widely used low-voltage (that is, less than 200 V) switch. It can be found in most power supplies, DC to DC converters, and low voltage motor controllers.
