Question

Problem 1 (15 Points) Multiple Choice Problems (only ONE correct answer ea than one choice will be considered WRONG. 5 points each). ch. More 1) In the circuit to the right, the Gate voltage is IV, the Source voltage is OV and the Drain voltage is 5V and Vtn is 1V. What mode is the transistor in? A. Active B. Saturation C. Triode D. Cutoff E. None of the above current to flow through the 2) In a NMOS transistor, increasing the VGS will allow induced channel. A. More B. Less C. No change D. None of the above 3) The graph shown below, what is on the x-axis? A. VGS B. VDS C. VDG D. None of the above

Explanation / Answer

1. Answer is Saturation region

Because Vgs-Vt < Vds

Vgs-Vt is overdriven voltage

Vgs-Vt >Vds then it is in linear or triode region

2. Answer is more

Increase in gate source voltage will attract more electrons into the channel and increase the depth of channel which will increase current flow

3. Vgs

This graph is Id vs Vgs
