1.A Si example is doped with 10^17 As atoms/cm^3, waht is the equilibrium hole concentration at 300K? where is Ef relative to Ei?
2.Estimate the intrinsic carrier concentration of diamond at700K (you can assume that the carrier masses aree similar to those in Si).Compareee the results with those for GaAs and Si. the result illustrates on reson why diamond is useful for high temperature electronics.
3. A GaAs device is dopeed with a donor concentration of 3*10^15 cm^-3, For the device to operate properly, the intrinsic carrier cconcentration must remain less than 5 percent of the total electron concentration. What is the maximun temperature that the device may operate?
2. What is the expected output frequency of a sample and hold system if fs= finput 3. Which is input frequencies will give an output frequency of 50 Hz when put through a sample and hold system if our sampling frequency is 488 Hz
A serial transmission is set up for 8 bits with odd parity. The first two bytes of data are 01110111 with parity bit 1 and 01101010 with parity bit 0. From this we know that there are no errors in transmission.

Let x(t) and y(t) be two real, periodic signals that are orthogonal to each other. Show that the power of the sum of the signals (i.e., x(t) + y(t)) is equal to the sum of the individual powers (i.e., Px + Py).
Line A extends from (2,2, 0) to (-2, 2, 0) and Line B extends from (2, -2, 0) to (-2, -2, 0). Each has a linear charge density l = 1 nC / m. You want to calculate the magnitude and direction of the electric field due to the two line charges for al..
A video signal contains light variations that change at a frequency as high as 3.5 MHz. What is the minimum sampling frequency for A/D conversion?
Mrs. Brooke owns a robot with an FSM brain. The robot walks from left to right along a paper type containing a sequence of 1's and 0's. On each clock cycle, the robot walks to the next bit.
Important information about Noise, Explain the role of the central limit theorem in the behavior of Additive White Gaussian Noise (AWGN).
A unipolar 16 bit ADC measures 0-10 volts full scale. a) What is the minimum resolvable voltage b) What is the percent quantization error c) What is the percent quantization error if a 1 volt max signal is input
Explain the operation of sequential logic devices and evaluate the output waveform in relation to the clock for QA, QB and QC in the subsequent circuit and show the binary sequence represented by these waveforms
There are 2 stages of pipeline. 1st stage: max delay 6.5ns, min delay 2.5ns. 2nd stage: max delay 5ns, min delay 2ns. Setup time, hold time and flip flop delays = 0.1ns.
how do we determine the direction of current in a multiloop circuit with more than one source of e.m.f?
