A BJT differential amplifier operating with a 0.5-Ma current source uses transistors for which β = 100, fT = 500 MHz, Cμ = 0.5 pF, and rx = 100Ω. Each of the collector resistances is 10 kΩ, and ro is very large. The amplifier is fed in a symmetrical fashion with a source resistance of 10 kΩ in series with each of the two input terminals.
(a) Sketch the differential half-circuit and its high-frequency equivalent circuit.
(b) Determine the low-frequency value of the overall differential gain.
(c) Use the Miller approximation to determine the input capacitance and hence estimate the 3-dB frequency fH and the gain-bandwidth product.
Can human eyes see this photon - Compute the size of the image formed on the retina of a fly sitting on a wall 3.0 m away.
The fly a kit slides are attached. Make sure the write-up is in your own words (do not just cut and paste). Focus on the importance of SAP for industrial engineers assignme.
Consider a vertical elevator whose cabin has a total mass of 800 kg when fully loaded and 150 kg when empty. The weight of the elevator cabin is partially balanced by a 400-kg counterweight that is connected to the top of the cabin by cables that ..

Research and determine how the data from a computer keyboard is translated into the binary code required for input to a computer. Remember to cite your sources. Can we use decoders for this function?
Compareand contrast Ecological Economics and Green Economics with NeoclassicalEnvironmental Economics. How do theirgoals and principles differ? Are any of them similar?
With CC connected, find ωP2. Then find the value of CC that will result in a unity-gain frequency ωt at least two octaves below ωP2. For this value of CC, find ωP1 and Ωz and sketch a Bode plot for the gain magnitude.
Determine the sheet resistance RSH (ohms/square), the contact resistance RC (ohms) and the doping density ND (cm-3) and draw the T- 1/λ curve where the semiconductor wafer is thinned, i.e. d is reduced.
Describe a tunnel-boring machine in detail and cite examples of their use. Particular emphasis should be placed on the cycle of operations for such a machine.
Determine the minimum acceptable wall thickness using thin cylinder theory and determine the minimum acceptable wall thickness using thick cylinder simulation software.
The parallel galvanized-iron pipe system of Fig delivers water at 20°C with a total flow rate of 0.036 m3/s. If the pump is wide open and not running, with a loss coefficient K = 1.5, determine (a) the flow rate in each pipe and (b) the overall pr..
