In the amplifier below, VTH = 0.5 V and λ = 0 for all the transistors, β1 = β3 = β5 = 2 mA/V2, β2 = β4 = β6 = 0.5 mA/V2, and VDD = 4 V. Resistors and capacitors are used for biasing purposes, and may be assumed to be very large. a. Find the operating point of the transistors. b. What is the overall small signal gain of the amplifier (vo/vi)?
