A voltage Va=23.03(kT/q) is being applied to a step junction diode with n- and p- side dopings of Na=10^17/cm^3 and Nd=10^16/cm^3. Ni=10^10/cm^3. Make a dimensioned log (p and n) versus x sketch of both the majority and minority carrier concentrations in the quasineutral regions of the device. Identify points 10 and 20 diffusion lengths from the depletion region edges on your sketch.
a certain ideal voltage generator is characterized as v(t) = 40 sin 377 t . If this generator is measured with a DC voltmeter, the instrument reads 12 volts, what is the rms value of this voltage waveform
Show the truth table for the following circuits: a. A 3 input NAND GATE (Inputs are A,B, and C and the output is Q) b. A 3 input odd parity circuit. (Inputs are A,B, and C and the output is Q) c. A two bit adder with inputs (A1,A0 and B1,B0) and outp..
a. Create 10000 random variables uniformly distributed between 2 and 4. b. Create a histogram to approximate the actual probability density function. c. Superimpose the actual probability density function to the above histogram.
Look up 8b/10b encoding and explain what purposes (NOTE: purposes is plural!) it serves. How would you implement an 8b/10b encoder
Three friends (Al,Bob and Chris) put their names in a hat and each draws a name from the hat.(Assume Al picks first, then Bob,then Chris). Find the sample space. Find the sets A,B,and C that corresponds to the events "Al draws his own name".
Determine for each of following 4 signals if it is bandlimited and, if yes, find the minimum sampling rate without causing aliasing. (a) x1(t) = cos(500pt) + sin(700pt); (b) x2(t) = sin2(50pt);
