Consider an n-channel MOSFET with parameters: Kn = 0.25 mA/N, Vtn = Vth = 0, Cgd = 0.04 pF, and Cgs = 0.2 pF. If the transistor is biased at Vgs = 3 V, the unity-gain bandwidth of the FET will be 626 MHz (b) 646 MHz 663 MHz 683 MHz.

An n-channel MOSFET has the following parameters: $$ \begin{aligned} \mu_{n} &=400 \mathrm{~cm}^{2} / \mathrm{V}-\mathrm{s} & t_{\mathrm{ox}} &=500 \AA \\ L &=2 \mu \mathrm{m} & & W=20 \mu \mathrm{m} \\ V_{T} &=+0.75 \mathrm{~V} & & \end{aligned} $$Assume the transistor is biased in the saturation region at $V_{G S}=4 \mathrm{~V} .(a)$ Calculate the ideal cutoff frequency. (b) Assume that the gate oxide overlaps both the source and drain contacts by $0.75 \mu \mathrm{m}$. If a load resistance of $R_{L}=10 \mathrm{k} \Omega$ is connected to the output, calculate the cutoff frequency. Repeat Problem $10.56$ for the case when the electrons are traveling at a saturation velocity of $v_{\text {sat }}=4 \times 10^{6} \mathrm{~cm} / \mathrm{s}$.
Refer to the MOSFET circuit above. Given Rsi = 50 Ω, R1 = 325.00 kΩ, R2 = 180.00 kΩ, and RD = 0.75 kΩ. If the transistor has an Early voltage of VA = 10^4 V, k = 0.7 mA/V^2, ID = 2.10 mA, and VTN = 1.50 V, what is the value of the small signal output resistance of the transistor?
