The question is below. Please include where you find the resource to answer this question. Thanks. As the gate length of MOSFET transistor shrinks to nanometer scale, the operation of MOSFET is limited by fundamental physical process. One of the most severe limitation is the inability to reach complete cut-off mode for nano
Please see attachment. a) Draw the Bode plot (on semi-logarithmic graph paper) of the transfer function. see attached aii) From the Bode plot, what would the approximate harmonic response of the above system to an input, u(t)=sin(2t)? Confirm your answer by simple calculation.
For this question, please leave out the proof. Assume the formula is already known. Also, instead of assuming a unit step of U(t) = 1(t), change the question to a sinusoidal input of U(t) = sin(2t). Please solve this question and explain all the steps in detail.
An RL circuit with switches is shown in the figure. Switch s1 remains closed and s2 remains open for a long time (steady-state). At t=0 switch s1 opens and s2 closes. Find V_1(t) for t > 0.
Hi, I know you do not do homework assignments but I am studying for a test tomorrow and these are practice tests with no answers and so I really need to learn how to do them. Could you please help me understand the entire problem (again, this is not a homework problem, just practice)? See the attachment.

Have four circuits. One takes 9Vdc, two 5Vdc, and last one takes 12Vdc. Have variable transformer for source. How do I calculate or choose the voltage needed to run all four circuits with out blowing them all up, and at the same time run each circuit by themselves or two at a time or three, etc. How do I know how much curren
Find Icq and Vceq for the circuit when Beta=100. I put the 60k and 30 k resisters in parallel and then did a thevenin equivalence on the parallel combination resistance and the 20k ohm resistor. Then, I did kvl around the b-e loop and got icq=.021ma and vce=.39v. Did I do the thevinin equivalence correctly? See the attach
In the complementary output rectifier, If Vs=26*sin 2*pi*60*t Volts, sketch the output waveforms vo+ and vo- versus time, assuming Vgamma=.6V for each diode. I don't understand the graphic questions. Will there ever be a time when the voltage goes negative? because it looks like a FWR. Thanks
