VI Characteristics of MOSFET

Procedure of VI Characteristics of MOSFET

Initial Settings

  • Ensure the 230V Power Supply is in proper with Tester.
  • Check the input supply of the kit and off the switches of the kit.

Experiment Steps

1. Transfer Characteristics

  • Connections are made as shown in the circuit diagram.
  • Switch on SW2 observe whether meter are reading 0.
  • Set both voltages to minimum position, and then switch on SW1.
  • Increase VDS voltage to maximum position.
  • Now slowly increase the voltage across VGS and note down the VGS and ID value and plot graph. Note: MOSFET turns on around 4V.
  • Repeat from step 2 for another value of drain voltage VDS.

Note: If the connections are made wrong the kit may get damaged. Please switch off the kit when not in use.
