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 $v_{\text {sat }}=4 \times 10^{6} \mathrm{~cm} / \mathrm{s}$.

00:01 Hi everyone in this question they have given four options which is b jst and igbt and then c which is mosf and m -o -s -f -e -t and d which is scr.
00:23 According to this four which have the most switching frequency we have to say most switching frequency application which device have.
00:33 So in this case we can say this for among these four we can say moseft has the least switching losses among the rest of all devices why the most soft why because this is the three terminal device with gate its drain and source terminals so we can say this is the metal oxide semiconductor field effect transistor so we can say here this stands for m m .o s f e t stands for metal oxide semiconductor field effect transistor.
01:25 So from this case, it has a three terminal device with gate drain and source terminal, current conduction between drain and source controlled by the voltage applied gate.
01:37 So, compare the favorably bipolar transistor in terms of the relatively high speed and the low loss operation.
01:45 So come so this is the high speed and relatively low loss operation and then it's our end high speed...
