Input Characteristics

Transistors  can be  operated in the switching  mode. If  base  current IB  is zero transistor is in  an ON  state  behaves as a switch. If  the base  current  IB is  sufficient to drive the transistor  into saturation, them  the transistor  behaves as closed  switch. The transistor  is a current driven device. The  base current  determines  whether it is in ON  state or OFF  state. To keep  the device  in ON state there should  be a sufficient  base current.
