An op-amp current gain amplifier is shown in given Figure.
Assuming an ideal op-amp, design the circuit such that the load current is Io = 5 mA for an input current of Is = 60μA.
A 78 Ohm lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75 Ohms?
Assuming that the feed point impedance of the complementary 0.475 l dipole is 70 + j0 ohms if it were fed in the center, calculate the distance Zf to use to obtain Zs = 50W for a signal frequency f = 1000 MHz.
Wing cracks, in the inspection of commercial aircraft, are reported as nonexistent, detectable, or critical. The history of a certain fleet shows that 70% of the planes inspected have no wing cracks, 25% have detectable wing cracks, and 5% have cr..
placing the compensator or zero such that it will cancel the open-loop pole at -1. For both compensators you design, show the corresponding closed-loop transfer functions and compare the transient responses (P.O. and Ts).
The data inputs I0 through I7 are wired as follows: I0 = I1 = 0, I2 = I6 = , I3 = I5 = I7 = 1; and I4 = D. (a) Determine the Boolean function that the MUX implements. (b) Implement the function using a 4×1 MUX with minimum extra logic gates.
A listener increases his distance from a sound source by a factor of 4.11. Assuming that the source emits sound uniformly in all directions, what is the change in the sound intensity level in dB
Find the armature current just after the power is applied and when the speed is 1500 rpm.
Consider the common-source amplier shown in Figure. The NMOS transistor has KP = 50 A/V2, L = 5 m, W = 500 m, Vto = 1 V, and rd = ∞. Determine the values of IDQ, VDSQ, and gm.
Design a four-bit shift register with a paralel load, usingD-flip-flops. There are two control inputs:shift and load. Whenshift t=1, the contents of the register are shifted by oneposition. New data are transferred into the register when load=1and..
A proportional control system is to be used to control the wing flap 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 with 5o of the set point.
Find the approximate saturated synchronous reactance XS at a field current of 380 A. Express the answer both in ohms per phase and in per-unit.
In a bridge rectifier the transformer is connected to 220V, 60Hz mains and the turns ratio of the step down transformer is 11:1. Assuming the diode to be ideal, find: i) Idc
