40-V power MOSFETs with low RDS(On) and deliver high power .

Nexperia’s 40-V power MOSFETs in the LFPAK88 package delivers more than 50 times  greater power densities. Electronic applications have progressed significantly in recent years and have inevitably increased the demand for an intrinsically rugged power MOSFET. Recently Nexperia has introduced new  MOSFETS   in the LFPAK88 package which has the  lowest drain to source resistance ( R DS(on) ) 0.55 mΩ ,   40-V power MOSFETs in the high-reliability  LFPAK88 package  for  automotive and industrial  applications. These devices are the lowest R DS(on)  40-V parts that Nexperia has produced . Nexperia claims these devices offer power densities more than 50 times greater than traditional D2PAK devices as well as improved performance in both Avalanche and Linear mode for higher reliability and increased ruggedness. The company attributes the performance increases to a combination of the latest high performance superjunction silicon technology wit...

Input offset current of Opamp

Image
 Welcome to  Techtronics. In this article,you are going to learn about the input offset current of Opamp, this issue is one of main non linearities of Opamp. Because of this non linearity issue system gets some error ,so here we are going discuss about how to reduces it.so, thanks to came here . At the end of the session you will get some knowledge about how to reduce practically this bias current. Definition of input bias current                             Ideally ,there is no current flow into the input terminal of opamp without giving any input voltage ,which means that both inputs are grounded (both inverting and non inverting input of opamp).But practically there are some input current flowing into the opamp due to fabrication of internal transistors and temperature.which is called input bias current I B+   and I B- .                   ...
