A young designer, aiming to develop intuition concerning conductingpaths within an integrated circuit, examines the end-to-endresistance of a connecting bar 10μm long, 3μm wide, and1μm thick, made of various materials. The designer considers:a) n-doped silicon withND=1018/cm3b) p-doped silicon withNA=1016/cm3c) aluminum with resistivity of 2.8μΩ*cmFind the resistance in each case. For intrinsic silicon, usen=p=ni=1.5*1010/cm3,μn=1350, μp=480. For doped silicon,assume μn=2.5μp=1200cm2/V*s
A 4 ohms resistance is in series with the parallel combination of a 20 ohms resistance and an unknown resistance R sub x. The equivalent resistance for the network is 8 ohms. Determine the value of R sub x.
Using the message signal m(t) = 1/(1+t^2) , determine and sketch the modulated signals for the following methods of modulation: (c) SSB modulation with only the upper sideband transmitted. (d) SSB modulation with only the lower sideband transmitted.
Find an expression for the rms (root-mean-square) speed of these particles, assuming them to be spheres of diameter and density
Write a 68000 assembly language subroutine, ROTMEM, which rotates the elements (words-size) of an array stored at location point to by (A0). The depth of the array is stored as the first element.
To understand dierent signal models To be able to model a discrete-time system and design simple signal processing algorithms.
Two identical CS amplifiers are connected is cascade. First stage is fed with a source Vsig having a resistance Rsig = 100k Ohm. A load resistance Rl = 10k Ohm is connected to the drain of the second stage.
A certain element has a phasor voltage of V=86.6+j50 V and the current I= -2.5+j4.33 A. The angular frquency is 200rad/s. determine the value of C to two significant figures with appropriate units.
A jet has 4 engines, A and B on the left wing, C and D on the right wing. Each engine gives a FAIL signal which is TRUE if the engine is broken, and is FALSE if the engine is working fine. The plane can fly as long as at most 1 engine on each wing..
Use Matlab to verify the above results and determine: a. The starting torque b. The maximum torque c. The slip at which the motor develops maximum torque d. Draw the torque-speed characteristic of the motor
Calculate the THD and Dynamic range for each case assuming ideal digital to analog conversion: i. N = 30 converter bits ii. N = 60 converter bits iii. N = 90 converter bits
What is the energy in joules stored in the capacitor below, The capacitor is shown with 10 volts on each side of it (plus on the left of the capacitor, - on the right), and C = 20 microfarads.
The power amplifier in a home theater amplifier has an output power of 200 watts. Assuming a Class B amplifier with the maximum theoretical efficiency is used, find the DC power delivered to the amplifier.
