      A bipolar junction transistor is made up of three pieces of silicon. Depending on what is added to the silicon, it will be either N-type or P-type. An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the layers are reversed.

      The basic transistor amplifier circuit is indicated below: It is called a "common emitter" amplifier since the emitter is common to both the input circuti and the output circuit. There are additionally three capacitors but they do not play a role in the basic transistor amplifier design which mainly involves setting DC voltages.

But the circuit shown above is symmetric, so either the right-hand light or the left-hand light can be "on." In fact, the state of the system can be flipped. If a signal is applied in the right place, the circuit will flip.

      The bias circuit shown in Fig. 3 is used when stability is a very important con- sideration. The circuit in Fig. 1, and the variation we created by adding an emitter resistor, are simplified versions of that circuit. In it, V,, has been eliminated; instead, Vcc is used as both the collector and base supply.

      A transistor that turns ON fully and OFF fully is called a SWITCH. When two transistors are cross-coupled in the form of a flip flop, any pulses entering the circuit cause it to flip and flop and the output goes HIGH on every second pulse. This means the circuit halves the input pulses and is the basis of counting or dividing.
