A cuboid of Germanium (Ge) has contacts all over its 2 x 1 mmends and point contacts exactly half way along its 5 mm length, atthe center of the 5 x 1mm faces. A magnetic field can be appliedparallel to this face. A current of 5mA is passed between the endcontacts of 4.8 mV with no magnetic field.(i) Using the corrected Hall voltage find the carrier density in the Ge sample.(ii) Estimate the conductivity of the Ge.(iii) What is the mobility of the carriers?(iv) Is it a p or n type semiconductor?
Plot accurately the gain and phase as functions of w with a matlab program you write. Attach plots and your own program. Note: Bode plots or any plots with logarithmic scale of either axis are NOT acceptable.
Seawater with a specific weight of 64.0 lbs/ft^3 is at a level of 4 feet above the centerline of the exit pipe. The tank is closed at the top and there is a pressure of 1 psig above the seawater. What is the velocity at the end of the pipe
In and Th are inputs and Out is the result. All parameters are 8-bit unsigned integers. A typical calling shows that the two inputs, In and Th, are passed on the stack and the return parameter Out, is returned in RegB.
A repeater with additive noise of 48μW and a power gain of 20 dB has 150μW of input signal power and 1.2μW of input noise. Calculate the input SNR, the output SNR, the noise factor, and the noise figure.
Invesitagtion of Intermodulation through an amplifier, An amplifier is designed to handle frequencies around 9 GHz. The bandwidth of the amplifier is 2 GHz with a center frequency of 9 GHz
four loads are connected in series across 110 volts D.C.THE loads fail to operate.a voltmeter connected in succession across each device reads 0 across the first three loads and 110 volts across the fourth load.What circuit fault is indicated at t..
Describe how an ideal inductor reacts to steady state DC and why. State the equation for finding the instanteneous current in an inductor during the transient period. Explain each part
Two delta-connvected loads are connected in parallel and powered by a balanced Y-connected system. The small of the two loads draws 10k VA at a lagging Power Factor (PF) of 0.75, and the larger draws 25k VA at a leading PF of 0.80.
Boron donor atome at a concentration of 10^15 cm^-3 are distributed uniformley throughout a silicon sample. The sample is then also doped with 6*10^15 cm^-3 of phosphorous. calculate the position of the Fermi level
For a certain source-free parallel RLC circuit, R=1k-ohm, C=3uF and L is such that the circuit response is overdamped. Write an equation for the voltage across the resistor if it is known that v(0-) = 9V and dv/dt|t=0+= 2 V/s
During an AP, the membrane potential typically moves from -70mV to +20mV and back again. In a cell with 10um radius and 1uF/cm^2, how many charges need to move across the membrane (and back again) to get this 90 mV voltage fluctuation?
The magnitude of the current in a RL circuit decreases at a rate of 2000 A/s at t=0 and 100 A/s at t=.2s. At what time has the energy stored in the inductor decreased 1 percent of its intial value.
