D 10.58 Design a cascode amplifier to provide a dc gain of 74 dB when driven with a low-resistance VE 10.4 generator and utilizing NMOS transistors for which VA = 10 V, 4.Cox = 200 mA/V?, WIL = 50, Ced=0.1 pF, and C = 1 pF. Assuming that R, = R, determine the overdrive voltage and the drain current at which the MOSFETS should be operated. Find the unity-gain frequency and the 3-dB frequency. If the cascode transistor is removed and R, remains unchanged, what will the dc gain, the 3-dB frequency, and the unity-gain frequency become?
