DependentSources and MOSFETs
Diagram of circuit, including measured resistance value. (5 pts)Measured resistance of resistor R=100.3 Ω
What MOSFET threshold voltage. (10 pts)
Fromthe data table obtained from the experiment the threshold voltage isapproximately 1.5V. Since current appears when voltage goes above1.5V.
Attach to this worksheet a table providing your measured gate-to-source voltage vs. drain current values and a plot of data. (15 pts)
Current I (mA)
4.What type of dependent source is the transistor behaving like? Why?(5 pts)
Thetransistor in this case is behavinglike a voltage dependent current source since the transistor controlsthe current that goes through the circuit based on the voltage on theMOSFET gate.
5.Estimated value of g for circuit. Annotate the plot attached to thisworksheet, indicating how the value of g was determined. (10pts)Usingexcel I obtained the linear part of the plot and calculated the slopeof best fit line of the graph. The slope obtained by Excel is 3.278which is the g for circuit.Estimateg is 3.278
6.DEMO: Have a teaching assistant initial this sheet, indicating thatthey have observed your circuits’ operation. (10 pts)
