Reconsider the three amplifiers introduced in Problem 1.25 above as transconductance amplifiers. Restate the specifications of each as a transconductance amplifier. Identify a figure of merit for a transconduc-tance amplifier like that suggested in Problem 1.26 above for a current amplifier. Use this to rank the three as transconductance amplifiers.
The prime mover rotates the armature at a speed of 1000 rpm. Determine the no-load voltage, the full-load voltage, and the torque required by the prime mover at full load if the full-load power required by the load is 3 kW
A combinational logic circuit has four imputs (A, B, C, and D)and one output Z. The output is 1 iff the input has three consecutive 0's or three consecutive 1's. Fore example, if A= 1, B = 0, C = 0, and D = 0, then Z = 1, but if A = 0, B = 1, C =0..
Find at least one article on the application of superconductivity in the commercial sector, and write a short summary, including all interesting facts and figures.
To meet the signal-to-noise ratio of the receiver, the received power must be at least 10 µ W. Assuming the two antennas are aligned for maximum reception to each other, including being polarization matched, what should the gain (in dB) of the tra..
A body attached to earth ground by an electrical conductor is at zero electrical potential. A charge of 25 C is added to the body. What is the potential of the body now. Explain.
Why is the idea of using electronic cash still so popular despite the many failures in the last few years
An engineer decides to set up an experiment to try this idea out. He decides to use a large metal plate or substrate as one electrode, then paint it and then place another electrode (with a smaller area) directly on top of the paint layer.
The electric field of a uniform plane wave propagating in lossless isotropic medium is E(x,t) = 60(pi)cos(3 10 t + 4x) ay V/m. The magnetic field at point (0,0,0) when t = 0 is 1A/m. The unit of t is second and the unit of x is meter.
A certain sample of pure quartz has a dielectric constant of 3.8, dielectric strength of 1.0 kV/0.0010 in, and a density of 2.6 Mg/m3. Assume the number density of dipoles in quartz is the same as the number density of SiO2 units.
A Si pn junction diode is described by its I-V equation, I?= Is exp (V?/V?) ,where V?=25mV, Is=10-14A . It is desired to derive constant drop and PWL models for the diode assuming an operating current between 1mA and 3mA.
The output power of the digital transmitter is 0 dBm and the link has a constant attenuation of 50.0 dB. At the input to the receiver, the equivalent AWGN noise power is – 70 dBm. Assume implementation margin is 0 dB when calculating BER in ..
