Question:
Calculate second-harmonic distortion in the common-source amplifier with a depletion load shown in Fig. 4.20a for a peak sinusoidal input voltage v̂i= 0.01 V and VDD= 3 V. Assume that the dc input voltage is adjusted so that the dc output voltage is 1 V. For simplicity, assume that the two transistors have identical parameters except for unequal threshold voltages.
Let W/L = 100, k€™ = 200 µA/V2, and λ = 0.Assume Vt1|VSB1=0 = 0.6 V, Vt2| VSB2=0 = ˆ’ 0.6 V, Ï•f = 0.3 V, and γ = 0.5 V1/2. Use SPICE to verify the result.
