Consider the circuit shown below. Assume that the transistor is in saturation, VTN = 1V and Kn = .02 A/V^2. Determine Vo and Vin when Vs = .45V the voltage at the source is 0.45). Show your work!

Explanation & Steps

Step (1): Determine drain current of NMOS transistor.

Step (2): Determine gate voltage and drain voltage using drain current in saturation mode of NMOS transistor.

Finally verify the mode of operation using the obtained value of gate and drain voltage. If the mode of operation correct, then the calculations in step (2) are correct. 

Otherwise, change mode of operation and calculate gate and drain voltage again. Re-verify mode of operation.

For the circuit shown in Figure 2, VDD = 5 V, and transistors M1 and M2 have properties µnCox = 200µA/V2, (W/L) = 10, Vt0 = 0.7 V, and λ = 0. You may neglect the body effect below, unless you are specifically asked to consider it. Figure 2. Circuit for Problem 2. a) Draw the circuit above, and label the drain, gate, source, and bulk nodes for both transistors, using labels VD1, VG1, VS1, and VB1 for the drain, gate, source, and bulk nodes of device M1, respectively, and similarly for M2. In total, there should be 8 labels in your schematic. For this part, assume the transistors are in saturation. b) Determine the valid input range for the circuit under consideration; that is, determine the range on the input voltage Vin such that transistors M1 and M2 are operating in the saturation region. Note that, in your analysis, you are not constrained to Vin values between 0 V and VDD, inclusive; e.g., if Vin = 100 V keeps both of the transistors in saturation, then Vin = 100 V should be included in your range of valid input voltages. Your answer to this part should take the form Vin,low ≤ Vin ≤ Vin,high ; hopefully, it is obvious that you are being asked to provide numerical answers for the lower- and upper-bounds Vin,low and Vin,high , respectively. c) For the valid input range that you determined in part (b), determine the corresponding output voltage range; that is, determine Vout,low ≤ Vout ≤ Vout,high when the input is constrained to Vin,low ≤ Vin ≤ Vin,high. . As before, you should report numerical values for the lower- and upper-bounds Vout,low and Vout,high, , respectively. d) Determine the "on voltage" VON2 (or, as in the Sedra/Smith textbook, the "overdrive voltage") and drain current ID2 of transistor M2 over the range of valid input voltages. Also, determine the drain current ID1 of M1 over the valid input range. e) If you were to consider it, would any of the transistors in the circuit above be affected by the body effect? If "yes," then list the device (or, devices, as the case may be). Qualitatively speaking, how would your answers to parts (b) and (c) change if you were to take the body effect into account? Explain your reasoning.
