Assume the vector AM contains an even number of elements. Develop a MATLAB script that asks the user for the vector AM and once the vector is found to contain an even number of elements, divide the product of its even elements by the sum of its odd elements without using the MATLAB functions prod or sum. Store the result in a variable called PDS. If AM is found to contain an odd number of elements, display an error message and prompt the user again for a vector with an even number of elements.

Your team’s task for this project is to simulate an NMOS transistor, compute the DC operating point and then design a bias network to properly operate the transistor in saturation. The transistor you will use is described by the spice model below:

ltSPICE:

.model NMOS0P5               NMOS(Level=1 VTO=0.7 GAMMA=0.5 PHI=0.8

+                              LD=0.08E-06 WD=0 UO=460 LAMBDA=0.001 TOX=9.5E-9 PB=0.9 CJ=0.57E-3

+                              CJSW=120E-12 MJ=0.5 MJSW=0.4 CGDO=0.4E-9 JS=10E-9 CGBO=0.38E-9

+                              CGSO=0.4E-9)

MultiSim:

.SUBCKT NMOS0P5 1 2 3 4

M 1 2 3 4 NMOS0P5 W=5u L=0.5u

.model NMOS0P5               NMOS(Level=1 VTO=0.7 GAMMA=0.5 PHI=0.8

+                              LD=0.08E-06 WD=0 UO=460 LAMBDA=0.001 TOX=9.5E-9 PB=0.9 CJ=0.57E-3

+                              CJSW=120E-12 MJ=0.5 MJSW=0.4 CGDO=0.4E-9 JS=10E-9 CGBO=0.38E-9

+                              CGSO=0.4E-9)

.ENDS NMOS0P5

In ltSPICE use the NMOS4 schematic component and a SPICE directive to properly load your model. In multisim use the component wizard and the MOS_N_4T schematic component. (see Figure 1 for proper multisim component creation). If you are using multisim.com online simulator, simply use a ‘NMOS’ device and input the Vt, Kn’ (shown as Kp) and W/L in the right side menu.

Figure 1. Custom component model

NOTE: for NMOS4 and MOS_N_4T you must connect the base to your source terminal as seen in Figure 3.

Figure 2. NMOS4 component

For the first part, you are to use the saturation equation for an NMOS with a Vt = 0.7V, K_n’ of 2.469 x10^-4 and a W/L of 10 (use 0.5u for L 5u for W in your simulation) to get a I_D of 4 mA. Once you find you V_OV value solve for your V_GS. Once your have your V_GS simulate the I/V curve you are familiar with using DC sweep on V_DS (start at 0V finish at 5V with 0.5V steps) and a fixed V_gs that you found using your equation. If you are using multisim.com you can simply show a transient line graph of 4mA Id.

For the second part, you are to find resistor values in the configuration shown in figure 3 to achieve the V_GS you solved for analytically in part 1 (use resistors in the 100k-1000 kOhm range for R_G1-2) as well as a V_D of 3V so that the transistor is operating in saturation. (use the DC operating point simulation to find these values, use V_DD = 5V).

Lastly, if we are to operate this transistor in deep triode, what is the resistor value r_ds?

Figure 3. Classical bias NMOS configuration

In summary:

Find V_GS analytically

Graph the I/V curve at this V_GS using DC Sweep

Find R_G1 R_G2 and R_D for a V_D of 3V

Show the DC Operating Point in saturation

Find r_ds analytically

In roughly 300 words, provide an analysis of the ethical scenario presented below. Be sure to explain how the ethical codes identified in the problem relate to the scenario, as well as any relevant connections to other case studies, concepts, or ethical theories discussed in class. Finally, provide a clear and explicit answer to the question raised in the scenario.

Scenario:

Engineer A is a senior engineer for a firm overseeing a large construction project. Engineers Y and Z are employees of the firm responsible for different components of the project, both reporting directly to Engineer A. While working on the project, Engineer Y observes an apparent safety violation in Engineer Z’s portion of the project. While the violation does not represent an immediate safety hazard, failure to address the issue could impact the overall safety of the project once completed. Engineer Y does have the relevant expertise to accurately identify the safety violation, but Engineer Y is not responsible for the portion of the project directly. Nevertheless, Engineer Y reports the safety violation in their next meeting with Engineer A.

Later, Engineer Z issues a complaint against Engineer Y, claiming that Engineer Y was overstepping their authority by reviewing Engineer Z’s work when it was not their responsibility to do so. Engineer Z claims that Engineer Y should have mentioned the issue to Engineer Z first, before reporting to the violation to Engineer A.

Question:

Was Engineer Y ethically permitted to report the safety violation to Engineer A?

NSPE Code of Ethics References:

II.3.a Engineers shall issue public statements only in an objective and truthful manner. a. Engineers shall be objective and truthful in professional reports, statements, or testimony. They shall include all relevant and pertinent information in such reports, statements, or testimony, which should bear the date indicating when it was current.

III.7. Engineers shall not attempt to injure, maliciously or falsely, directly or indirectly, the professional reputation, prospects, practice, or employment of other engineers. Engineers who believe others are guilty of unethical or illegal practice shall present such information to the proper authority for action.

III.1.a Engineers shall acknowledge their errors and shall not distort or alter the facts.

III.1.b. Engineers shall advise their clients or employers when they believe a project will not be successful.

Thinking about fundamental objectives and means objectives is relatively easy when the decision context is narrow (buying a telescope, renting an apartment, choosing a restaurant for dinner). But, when you start thinking about your strategic objectives -- objectives in the context of what you choose to do with your life or your career -- the process becomes more difficult. Spend some time thinking about your fundamental strategic objectives. What do you want t accomplish in your life or your career? Why are these objectives important?

Try to create a fundamental objectives hierarchy and a means objective network for yourself. Obviously this will change over time and as your career and personal situation changes, but, it is an interesting exercise to undertake. Answer in 2 paragraphs

Using Arduino:

Emulate dots and dashes telegraph transmission using a button and two LEDs. For instance, if a button is held longer than 500ms, then the red LED will turn on to represent a dash "-". and a short press will turn on the green LED to represent a dot ".". The problem can be approached as a state machine where the states could include "wait_on_press", "delay_500ms", and "read_btn_val".
