Now that we have discussed all the above three, let us try to compare some of their properties.
| TERMS | BJT | FET | MOSFET |
| Device type | Current controlled | Voltage controlled | Voltage Controlled |
| Current flow | Bipolar | Unipolar | Unipolar |
| Terminals | Not interchangeable | Interchangeable | Interchangeable |
| Operational modes | No modes | Depletion mode only | Both Enhancement and Depletion modes |
| Input impedance | Low | High | Very high |
| Output resistance | Moderate | Moderate | Low |
| Operational speed | Low | Moderate | High |
| Noise | High | Low | Low |
| Thermal stability | Low | Better | High |
So far, we have discussed various electronic components and their types along with their construction and working. All of these components have various uses in the electronics field. To have a practical knowledge on how these components are used in practical circuits, please refer to the ELECTRONIC CIRCUITS tutorial.
