-A silicon diode has a doping profile such that ND = ax3. What is the depth of the junction assuming the p side is uniformly doped with NA per cubic cm. Assume the x origin is at an ideal ohmic contact on the n side of the diode.(assume T=300K).
-Sketch the energy band diagram for a Si p/n+ diode doped with NA acceptor and ND donor atoms. Assume both sides are non-degenerate.
-For the diode in problem 1b, if NA = 1015 and ND =1016 what is the built in potential (numeric value) of the diode?
-What is the origin of avalanche breakdown in a diode?
The output of an exclusive-NOR function is false only if exactly one of the inputs is true. Show the truth table of a two-input exclusive-NOR function, and implement it using AND gates, OR gates and NOT gates.
a generic rectifier is supplied from a 115v 60hz ac source and operates with a firing angel of 30 degrees. For the output voltage of the rectifier find: The dc component The rms value othe ac component
A) Write the KCL expression for this circuit and set it equal to zero. B) Find the voltage of Vo. C) Use your value of Vo. The final step is to use the inverse phasor-transform operation to transform this value.
A 2000kW synchronous motor operates at a three - phase line-to-line voltage of 4kV. It has a synchronous reactance of 4 ohms per phase. Calculate a) The nominal full load current of the machine when the excitation voltage E0 ( line - to-line) is 4k..
The purpose of this problem is to show you the connection between Fourier series and linear algebra. For simplicity, we will consider a finite basis. All questions will be referred to the following basis B = {1, sin(400t), cos(400t), sin(800t), cos..
a beam of polarized light of intesity I0 passes through a sheet of ideal polarizing material. The polarization axis of the beam and the transmission axis of the sheet differ by 30 degrees. What is the intensity of emerging light
Design a series resonant circuit to have a bandwidth of 400 Hz using a coil with a Ql of 20 and a resistance of 2 ohm. Find the values of L and C and the cutoff frequencies.
A series circuit has a DC voltage source (56 volts), a resistor, (72 ohms), a capacitor (82 farads), and a switch. The capacitor is initially uncharged and the switch closes at t=0.
In the "far field" region, show that the electric field intensity of a linear electric quadrupole decays much faster in space than 1/R3 for the electric field intensity produced by an electric dipole and 1/R2 for an electric monopole.
As a project manager on a product development team for a fast responding digital thermometer useable in high temperature applications (degrees C), you are asked to create a product development plan that addresses items
What would be the minimum allowable sampling rate for a pulse-duration modulator if it is required to handle a baseband frequency range from 50 Hz to 10 kHz
The bellows, diaphragm, and Bourdon tube pressure sensors all exhibit second order time response. This means that a sudden change in pressure will cause an oscillation in the displacement and, therefore in the sensor output.
