The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A typical use of these transistors is as a switch for moderate voltages and currents, including as drivers for small lamps, motors, and relays. [1] In switching circuits, these FETs can be used much like bipolar junction transistors, but have some advantages: high input impedance of the insulated gate means almost no gate current is required
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...

The circuit consisting of the commutating arms and the source providing the commutating voltage. commutating group A group of principal arms which commutate cyclically among themselves without intermediate commutation of the current to other principal arms. commutation capacitor A capacitor included in the commutation circuit to supply ...
The circuit is insensitive to the input voltage variations and the transistor stays firmly in active linear region. The input resistance is high because of the series negative feedback. The cutoff transistor breaks the connection between its input and output. As a result, its input voltage does not affect the output voltage.
