BJT – Bipolar Junction Transistors

A Bipolar junction transistor, commonly known as BJT, is a Si or Ge semiconductor device that is structured like two p-n junction diodes connected back to back. It has two outer regions which are the emitter and collector and another region in the middle known as the base. The bipolar junction transistor is called bipolar … Read more

Difference between mico processors and micro controllers

  Microprocessor It has many support devices like ROM, Read-Write memory, Serial interface, Timer, I/O ports etc. All these support devices are interfaced to microprocessor via a system bus. All support devices in a microprocessor based system are external.  The system bus is composed of an address bus, data bus and control bus. Microcontroller All the support … Read more
