Rangkaian Penguji FET| Mosfet

MISFET or FET is a related term meaning insulated-gate field-effect transistor, and is almost synonymous with MOSFET. This device used for amplifying or switching electronic signals. The basic principle of the device adalah voltage on the oxide-insulated gate electrode can induce a conducting channel between the two other contacts called source and drain. The channel can be of n-type or p-type, and is accordingly called an NMOSFET or a PMOSFET (also commonly nMOS, pMOS). It is by far the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common.

Circuit symbols Mosfet

This circuit is used to test N-Mosfets, whether it works or not. If it is not working, the LED will not flash. If Mosfet is working it will operate in the astable multivibrator circuit causing the Led to flash.

This circuit can test almost any N-Mosfets As a common emitter buffer that also drives the led as it receives pulses from the Mosfet drain, this circuit uses the NPN transistor
