Question

if ids (the drain current) was 0 for Vgs= 1V and all values of
Vds, explain why?

If Vgs=1V was NOT sufficient to create a channel in the NMOS
transistor, what does this tell you about the value of Vt?

Answer #1

An n-channel enhancement mode MOSFET has a drain current of
1.5mA when VGS=VDS=3V. Using this information, answer the following
questions about this MOSFET:
Given Kn=500uA/V2 , calculate values for ro, gm, and VTN of this
MOSFET when the drain current is 1.5mA. Be sure to show work and
include units for full credit.

A friend is behind the computer generating values from X∼Exp(λ),
but won’t tell you whatλis. She will, however, tell you 35
different random values from the distribution,X1 through X35.
1. Explain what the population and parameter are for this
setting.
2. Based on the data your friend gives, you decide your best
guess forλshould be 1/X, where X=(X1+···+X35)/35 is the average of
the 35 numbers. Explain why this is a reasonable statistic to use
based on your knowledge of the...

1.) a) Is the process of KNO3 dissolving in water
spontaneous at all temperatures studied? Is it spontaneous at
higher or lower temperatures? Briefly explain.
b) Is the reaction in (a) one that gives off heat or requires
heat? Briefly explain.
c) Is your value of ΔS consistent with the expected change in
disorder for the reaction in Equation 1? Briefly explain.
2,) A few compounds exist whose solubility decreases as the
temperature increases. How would the sign (positive, negative,...

Ratio analysis is important to all businesses regardless of
product or service sold. Each industry has averages benchmarks in
which to compare your companys’ individual performance. Please
think about and answer the following questions. Remember, these
questions are asking for you to be creative and answer the
question, ‘HOW’, I am looking for real
possibilities that you might try to accomplish in ‘your’
company.
1.Choose EITHER a service or product that you are producing and
selling. Tell me about your...

Instructions: Be sure to define all random variables/events used
in probability calculations. You should obtain “exact”
probabilities from R rather than giving approximate probabilities
using the 68-95-99.7 rule. Provide any code you use (final computed
values are not sufficient). I strongly recommend that you create a
Jupyter Notebook for this assignment, embedding your written
comments in Markdown cells.
