The surface concentration is fixed at N0=1.8e20/cm^2 when diffusing boron into a uniformly doped n-type substrate. The atomic diffusion constant for boron in Si at the temperature of 950 C is 3.0e-15 cm^2/s. calculate the metallurgical junction depths for the following conditions A)Nd=1.0e15 /cm^3 for 30 min B)Diffused at 950 C for 1 hr 30 min with Nd=1.5e16.
A 440-V, 60Hz, 4-pole, delta connected three phase induction motor has the following parameters in ohms/phase. R1= .3, X1= .9, R2=.6, X2=.9 Rc=150, Xm=60 If the rotational losses are 6% of the developed power A.) determine the efficiency when i..
An engineer is required to survey a nonrectangular plot of land but is unable to measure side UT directly (see Figure 2.11). The following data are taken: RU=121.0m, RS=116.0m, ST=83.5m, angle RST= 113 degrees
Given a course voltage of 10V, a source resistance of 10 ohms, a 10mH inductor, and a 5nF capacitor, choose a load resistance and draw a circuit that will have an underdamped (decaying sine wave) second order transient response.
Describe why the intrinsic carrier concentration changes with temperature. This would include from very cold temperatures to 600K+ temperatures. Why does an extrinsic semiconductor become intrinsic above ~ 500K
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
Flip-flops must be in what mode (Set, Reset, Hold, or Toggle) in order to divide a clock's frequency when building a counter What is the advantage of a synchronous counter as compared to a ripple counter
Determine the volumes of each of these semiconductors that will on avg contain one hole. The intrinsic carrier concentrations are ni=1.02*10^10 cm^-3,ni= 2.1*10^ cm^-3, and 10^-7 cm^-3.
The excitation branch impedances are given referred to the high-voltage side of the transformer. a) Find the equivalent circuit of this transformer referred to the high-voltage side.
Fibonacci numbers are the numbers in a sequence in which the first two elements are 0 and 1 and the value of each subsequent element is the sum of the previous two elements. Write a MATLAB program that generates the first 30 Fibonacci numbers
Some research data is provided to you for the purpose of learning to use Matlab features of polynomials and curve fitting, file name: mydata You may load the data to your computer by typing mydata =load(‘path of the mydata').
A wave propagates 50m through a dielectric of region 1. Region 1 is lossy. Here, f= 0.6 Np/m. At an interface to region 2, the reflection coefficient is r =0.2+j0.5. The wave then propagates 50m back into region 1 from where it originated.
