1. Transfer curves for three W’s of PMOS. Explain how PMOS W affects transfer curve.
2. Compare the simulated switching threshold with calculated one.
3. List the reasons for keeping PMOS wider than NMOS
4. Will the inverter response be same if instead of width you change length of PMOS instead of width

Database System Question

An automobile part trading company would like to store the following attributes for each
part in a database table:

PartNo: 10 bytes
Name: 30 bytes
UintMeasure: 5 bytes
UnitCost: 4 bytes
UnitPrice: 4 byes
QtyOnHand: 4 bytes
QtyOnOrder: 4bytes
PreferredSupplier: 30 bytes

Consider a disk with block size of 512 bytes and block pointer of 6 bytes long. Each record has a unique value of PartNo.
There are altogether 50,000 parts in the company.

Compute the following:

i) The number of file blocks required for storing the part records.

ii) The percentage of disk space saving achieved by implementing PartNo as primary index from implementing it as secondary index.

iii) The percentage of improvement on number of block accesses required for searching a product record based on PartNo’s value achieved by implementing PartNo as primary index from implementing it as secondary index.

What is the operational difference between combinational circuits, storage elements, and sequential circuits?

You are a homeowner and you have decided to invest some time into developing a temperature control system in your house instead of paying someone to do this work. You have available to you a microcontroller of your choice a well developed Kernel and your task is to write software to perform the temperature measurements and adjust the temperature accordingly. Provide a list of tasks you would need to realize your project (you can consider interrupts service routines to be tasks as well). Note:You do not have to write any code to solve this problem, but you must list the tasks you will need and draw a block diagramof the software system (show the states you could operate in and how your tasks can get into and out of those states. (Use the ideas used in the mC/OS-II or mCOS).

Fourier Transform. Discuss the effects of multiplying a time domain signal by a sinusoid (including multiple times) has on both the time and frequency domain representations, as well as the practical use of the method, i.e. summarize the conceptual understanding within 100 words.

1. Write MIPS assembly code to sum “n” positive integers. For example, n=5, read 5 numbers in memory (“.data” section) and add them together.

2. Write MIPS assembly code to calculate N-factorial. Read n from the memory. (Hint: use “.data” to define the content in a memory location)

q1) using Matlab

make a code that allows a user to enter a function like fractional function and cubic liner function then the Matlab send a domain, range, continuity

Explain the mechanism of a generic photodiode.

Single molecule devices are attractive to certain applications where small size and high capacity are both desirable. In terms of electrical conductivity capacity, most people would thick metal is the best and carbon based materials would be bad; is it true (or) not?

Provide an example to proof your argument.

?magine a transistor with 7 nm size. What we mean by that 'size' please explain that ?
