    RASPBERRY PI input voltage detection

    I am assuming you are getting digital signals at these voltage levels. In that case, you need to use level translator circuit. Please search online to see what are different level translator ICs available that can converter the 5V/12V/24V signal levels to 3.3V level.

    LTSpice - How to copy schematic and get a quality image

    Use Xcircuit for such uses. It gives you a postscript output which is of the highest quality suitable for thesis and publication.

    Opportunities in MNC's after completing Ph.D in VLSI ?

    I myself am going to join as a lecturer so cant give you any useful suggestion. I have seen that most of the VLSI related jobs in india tend to be testing type which requires a good knowledge of testing basics, scripting( like tcl,perl etc) and some digital design knowledge.

    Thickness of dielectric towards capacitance?

    The blue curve in this figure shows how the capacitance varies bfore inversion and after inversion. **broken link removed** Before inversion it decreases with thickness and afte inversion , due to the mobile carriers availble, the capacitance inreases.

    How can I measure Gm with Hspice?

    use the option .op this will print the details of your transistor in the output file.The gms of various transistors and thier regions of operation will be printed.

    sketching numeric vs time

    what do you mean by "does not plot versus time" ? Is the program plotting the values based on their index number ? If so , then you have to check if you gave the plot command correctly.
