1. MOS Band Diagrams. Consider four simple cases of the MOS capacitor, all combinations of low gate metal work function (e.g. Al qΦM ≈ 4.05 eV), high gate metal work function (e.g. Pt qΦM ≈ 5.15 eV), n+type silicon and p+type silicon substrate. Assume the substrate is highly doped, such that EF coincides with EC (n+) and EV (p+) respectively. ThConsider four simple cases of the MOS capacitor, all combinations of low gate metal work function (e.g. Al qΦM ≈ 4.05 eV), high gate metal work function (e.g. Pt qΦM ≈ 5.15 eV), n+type silicon and p+type silicon substrate. e SiO2 thickness is 2 nm. Please assume silicon electron affinity is qXS = 4.05 eV and band gap is EG = 1.1 eV.
(a) Sketch the four band diagrams across all MOS structures in equilibrium (VG = 0 V).
(b) Sketch the four band diagrams exactly at threshold (VG = VT), as the surface is inverted. Is the threshold voltage VT >0 or <0 in each case?
If the peak-to-peak voltage of a sinusoidal waveform extends vertically 6.4 divisions and the oscilloscope vertical sensitivity was set to 0.5 volts/division, what would be the reading of a multimeter using both the AC and DC scales
From a large lot of new tires, n tires are to be sampled by a potential buyer, and the number of defectives X is to be observed. If at least one defective is observed in the sample of n tires, the entire lot is to be rejected
design must mention the values of the resistors, capacitors, average and maximum current through the diodes, transformer turn ratio and the current carrying capacities of the transformer coils. Present these values neatly in a tabular form.
where fc is the carrier frequency, Ac is the carrier amplitude, µ is the modulation index, and x(t) is the baseband message signal. We assume that x(t) has absolute bandwidth W

A twelve pole, 480V, 60Hz synchronous motor has a reactance of 5 ohm. The field current is adjusted so that the equivalent field voltage Ef is 520V (line-to-line). Calculate the following: (a) Maximum torque. (b) Power factor at the maximum torque..
A 100-μF capacitor is initially charged to 100V. We want 90 percent of the internal energy to remain after one minute. What is the limit on the leakage resitance for the capacitor.
1)Design the following function in BiCMOS using the least amount of transistors (RTL not allowed). z= (AB)' + (CD)' 2)Calculate the Emitter current through a loading Resistance of 10k such that VOH=2.3V.
can you solve the attached file its only one question ltbrgt ltbrgtam expecting good price on it... ltbrgt ltbrgt
