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.

Figure P7.33 shows a discrete-circuit amplifier. The input signal vsig is coupled to the gate through a very large capacitor (shown as infinite). The transistor source is connected to ground at signal frequencies via a very large capacitor (shown as infinite). The output voltage signal that develops at the drain is coupled to a load resistance via a very large capacitor (shown as infinite). All capacitors behave as short circuits for signals and as open circuits for dc. (a) If the transistor has Vt = 1 V, and kn = 4 mA/V2 , verify that the bias circuit establishes VGS = 1.5 V, ID = 0.5 mA, and VD = +7.0 V. That is, assume these values, and verify that they are consistent with the values of the circuit components and the device parameters. (b) Find gm and ro if VA = 100 V. (c) Draw a complete small-signal equivalent circuit for the amplifier, assuming all capacitors behave as short circuits at signal frequencies. (d) Find Rin, vgs/vsig, vo/vgs, and vo/vsig.

Consider the circuit shown in Figure 2 below, with gm1 = 100 mA/V, gm2 = 20 mA/V, gm3 = 3 mA/V, R1 = 2 kΩ, R2 = 1 kΩ, VDD = 5 V, and all NMOS devices are in saturation. Channel length modulation and the body effect should be ignored for this problem. (And, hopefully, it is obvious that gm1, gm2, and gm3 correspond to the device transconductances of NMOS devices M1, M2, and M3, respectively: if this wasn't obvious, note that the next time you see something like this, I probably won't spell it out for you so explicitly. if at all, so please make a mental note of these kinds of things.) a) Determine the numerical small-signal voltage gain: i) Av = Vout/Vin in units of V/V and ii) |Av| in units of dB. Be sure to indicate whether your numerical answers are positive-valued or negative-valued (numerical answers with ambiguous signs will receive little, if any: credit, partial or otherwise). List your numerical answers in proper engineering notation format with appropriate units, and show your work. b) Determine the numerical small-signal resistance "seen" looking into node Vin. List your numerical answer in proper engineering notation format with appropriate units, and show your work. c) Determine the numerical small-signal resistance "seen" looking into node Vx. List your numerical answer in proper engineering notation format with appropriate units, and show your work. d) Determine the numerical small-signal resistance "seen" looking into node Vy. List your numerical answer in proper engineering notation format with appropriate units, and show your work. e) Determine the numerical small-signal resistance "seen" looking into node Vout. List your numerical answer in proper engineering notation format with appropriate units. and show your work.
