5. You are given a MOSFET biased as shown in the figure. i) Sketch the drain current Ip when Vo is ramped up from 0V to 3 V in a log scale. log(ID ↑ I, 2 0 ) The MOSFET has switched through different operation regions (inear, saturation, subthreshold) during the ramp-up ii) The MOSFET has swit Label the different regions in the graph as you plot the curve above. iii) In dicate the values Vo's that mark the different...
Explain the answer
1. Consider the following MOSFET characteristics. What type of device is it? A. N-channel depletion-mode MOSFET B. N-channel enhancement-mode MOSFET. C. P-channel depletion-mode MOSFET. D. P-channel enhancement-mode MOSFET. Ip(mA) 1.5 1.0 0.5 V 00 V 0 0 2.0 4.0 6.0 Consider an n-channel MOSFET. Assuming no interface charge due to defects and/or traps, how would the the following parameters change when the oxide thickness is reduced? The flat band voltage VFB A. Increase B. Increase; c. Unchange:...
3. Many parameters of crystals are dependent on the band gap. a) From the optical absorption spectrum of a certain semiconductor, one finds that the longest wavelength of radiation absorbed is 1.40 m. What is the band gap for this semiconductor? Explain how the band gap gives rise to this behavior. b) What band gap would be needed to make blue (450 nm) LEDs? Explain why. c) Most of the sun's radiation has wavelengths shorter than 1000 nm. For a...
What is an enantiomer ? How many enantiomers does limonene have ? How many enantiomers does Eugenol have ? Draw the enantiomer for each of the compounds below. For both cyclohexene and methylcyclohexene, determine the number of signals that your NMR spectrum has. What are the differences in the spectra and why does the spectrum for cyclohexene show fewer signals than the number of protons present in the molecule?

1. (8 points total) A parallel plate capacitor whose plates have area A and plate separation d is connected to a battery. While the capacitor remiains connected to the battery, describe quantitatively what will happen to the charge on the capacitor if each if the following actions occur. That is, explain numerically how the magnitude of the charge on the capacitor in each circumstance compares to the original a. (3 pts) The distance between...
