A. (10 pts) Implement the voltage amplifier shown below using an ideal op amp circuit. You have o...
A voltage amplifier (not necessarily an op amp) has a gain of 100 V/V when its output is left open-circuited. However, when the amplifier’s output is loaded with 1.0 kΩ, the gain is only 85 V/V. The same voltage amplifier has an input impedance of 10 kΩ. If the amplifier’s output is left open-circuited but the source driving the amplifier has a Th´evenin resistance (that is, a source impedance) of 150 Ω, then the gain will be less than 100...

Assuming an ideal op-amp, design an inverting amplifier with a gain of 26 dB having the largest possible R1 value under the constraint of having to use resistors no larger than 1 MΩ. If the input voltage source of this amplifier has an internal resistance r0 = 50 kΩ, how will this affect the gain? Design a solution that will eliminate the effect of the internal source resistance without having to change the values of R1 and R2.
