Evaluate the slew rate, and theamplifier specification in terms of conduction angle…Suppose we have a signal source with an internal (i.e., Thévenin) impedance that is always less than 1000 Ω, but is variable over time. Using the components listed in TableP13.36 , design an amplifier that produces an amplified version of the internal source voltage. The voltage gain should be −20±5 percent.

NOTE : KINDLY ELABORATE BRIEFLYAssume for a moment that perfectly accurate resistors were available for feedback networks; that is resistor tolerance is 0%. Then any deviation from the value set by the feedback resistor ratio is caused by insufficient raw op-amp gain. What minimum raw gain would be needed to get within 1% if an intended overall gain of 10? What if the intended gain is 100 instead?Suppose the amplifier shown has a differential-mode gain of 2500 and a CMRR of 80 dB. What is the output voltage if V1 = 5.001 V and V2 = 4.999 V?

Indicate the assumptions you take in your transactions.Given in the figure is a two-stage amplifier design that employs negative feedback. Answer the following questions. Use the notation (R1 + R2 + ... + Rn) for series resistors and (R1 || R2 || ... || Rn) for parallel resistors for clarity and ease. Assume that the transistors are already biased properly in the saturation region and ro1 = ro2 → ∞. Also assume that the capacitors have infinite capacitance. 1.)
