The cascode amplifier is given below. The transistors are identical operated at Vov $$=$$ $$0.2\mathrm{V},\mathrm{Vtn}=0.5\mathrm{V},\mathrm{Vtp}=?0.5\mathrm{V},{\mathrm{V}}_{\mathrm{DD}}=2.5\mathrm{V},{\mathrm{g}}_{\mathrm{m}}=10\mathrm{mA}/\mathrm{V}$$ and $${\mathrm{kn}}^{?}=400?\mathrm{A}/{\mathrm{V}}^2$$. and $${\mathrm{kp}}^{?}=200?\mathrm{A}/{\mathrm{V}}^2??=0.05{\mathrm{V}}^{?1}$$. a. Determine $${\mathrm{I}}_{\mathrm{D}}$$. b. Calculate W/L ratio for each transistor. c. Find $${\mathrm{V}}_{\mathrm{G}2}$$ and $${\mathrm{V}}_{\mathrm{G}3}$$ if transistors are to be remained in saturation region. d. Find output resistance and voltage gain of amplifier. e. Determine the minimum and maximum value of signal swing at the output for transistors to remain in saturation.
