For the following common source MOSFET nMOS circuit with the given output IV characteristic with VDD = 10 V, a. Determine the value of RD to allow a saturation ID of exactly 325 mA to flow. Make sure to pick and specify the value of VGS that you used (10) b. For this value of RD, if you were to increase VGS to 5 V, would you be in ohmic or saturation/active regime of operation? (5) For the following common source MOSFET nMOS circuit with the given output IV characteristic with VDD = 5 V, a. Determine the value of RD to allow a saturation ID of exactly 120 mA to flow. Make sure to pick and specify the value of VGS that you used (10) b. At the value of VDS at which ID = 120 mA is flowing, estimate the fraction of the channel that is pinched off. Make sure to explain your reasoning carefully. (10)

1) What's the name and function of this circuit? 2) What type of transistor is represented on top and bottom (respectively)? 3) Write equations relating to NMOS and PMOS drain currents. 4) Write an equation relating vDS and VS'D'. 5) Write equations relating NMOS gate to source voltage and PMOS source to gate voltage in terms of VIN and VDD. 6) What is the condition for VIN so that the NMOS would not be in Cutoff (Write appropriate equation or inequality)? 7) True or False? If drain current in MOS is zero, then it can only be in Cutoff region. 8) Yes, or no? Can a MOS be in saturation region if its drain current is zero? 9) Yes, or no? Can a MOS be in triode region if its drain current is zero? 10) True or False? If a MOS is in Cutoff, then its source to drain voltage is always zero. 11) True or False? If the gate to source voltage of a MOS is greater than the threshold voltage and the drain current is zero, then the drain to source voltage must be zero. Suppose VDD = 6V, Kn = 1.0 mA/V2, Vtn = 2 V, lambda_n = 0.0, Kp = 1.75 mA/V2, |Vtp| = 1 V, and |lambda_p| = 0.0 12) Let vIN = 2 V. Determine the value of iD and vout. 13) Let vIN = 4 V.
