Applications of Microcontroller

The reason I find microcontrollers fascinating is that they have been and continue to be such an important part of the electronics industry.  Over the past decade and more microcontrollers have been creeping into our daily lives.  Figure 1 shows how microcontrollers increased in popularity from 1991 through 1996. In today’s...

P-N Junction Diode

A p–n junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor. It is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy (growing a layer of crystal doped with one type of dopant on top of a layer of crystal doped with another...
