The initial voltage across the capacitor shown in Figure is vC(0+) = 10V. Find an expression for the voltage across the capacitor as a function of time. Also, determine the time t0 at which the voltage crosses zero.
The required exposure energy for a positive photoresist is 140 mJ/cm2 and for a negative photoresist is 9 mJ/cm2. Assuming negligible times for loading and unloading wafers, compare the wafer throughput for positive photoresist and negative photor..
A proportional control system id to be used to control the wing flaps of a jet airplane. The wind load is expected to cause as much as 600 in*lb of torque. The system should be able to keep the flaps to within 5 degrees of the set point.
Each window and door has a switch attached such that the contacts close when a door or window opens. Draw a ladder logic diagram that will turn on a light if one or more windows are open or if both doors are open.
A power amplifier has a gain of 20 dB and an input level of 2 volts. Assuming that the input and output impedances are the same, what is the voltage level at the amplifier output
Design a network that accepts as input one unsigned 8-bit number (which refreshes every clock cycle and is never 0) and keeps a running sum until the sum exceeds 1000. The network outputs both the sum and the number of additions required to reach ..
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.
Using a slotted line, the voltage on a lossless transmission line was found to have a maximum magnitude of 1.5 V and a minimum magnitude of 0.6 V. Find the magnitude of the load's reflection coefficient 'Omega'.
As typical in practice, the transformer taps are adjusted in steps, with each step changing the tap ratio by 0.625%. Because of the varying voltage drops caused by changing loads. LTCs should be operated to regulate the bus voltage.
Given: Si is doped with boron atoms; concentration of boron atoms is 1014 cm-3. Find: carrier concentration in Si at T = 300 K. (Hint: use Principle of Space Charge Neutrality) Find: Ei - position of Fermi level in intrinsic Si at T..
In a single-phase rectifier the input current can be approximated to have a triangular waveform every half cycle with a peak of 10A and a base of 60. Calculate the rms current through each diode.
Calculate the line parameters R', L', G', and C' for a coaxial linewith an inner conductor diameter of .5 cm and an outer conductordiameter of 1 cm, filled with an insulating material where μ =μ0, εr = 4.5, and σ =10-3 S/m.
