A silicon sample is 85x10^-6 m in length and has a cross-section of 20x10^-6 m x 6x10^-6 m. It has been uniformly doped with Arsenic with a doping density of 4.5x10^15 cm^-3. Assume the temperature is 300K and mobilities are u_n = 1300 cm^2/Vs and u_p = 450 cm^2/Vs.
a. What are the majority and minority carrier concentrations?
b. What is the resistivity of the sample?
c. What is the resistance (end-to-end) of the sample?
d. If one end of the sample is connected to ground and the other end is connected to a +3V supply, what will be the current through the sample?
e. What percentage of the current will be due to minority carriers?
f. What will be the average drift velocity of the majority carriers?
A load Z draws 12 kVA at a power factor of 0.856 lagging from a 120-V rms sinusoidal source. Calculate (a) the average and reactive powers delivered to the load, (b) the peak current, and (c) the load impedance.
find the Laplace transformation to find the v(t) that satisfies the following firs-order differential equation : a) 500 dv(t)/d(t) +2500 v(t)= 0 , v(-0)= 100V b) dv(t)/d(t) +200v(t)= 400u(t)V , v(-0)= -100V
AN SSB signal is generated by modulating a 5 MHz carrier with a 400 Hz sine tone. At the receiver, carrier is reinserted during demodulation, but its frequency is 5.00015 MHz rather than exactly 5 MHz. How does this affect the recovered signal
