Assuming an ideal op-amp, design an inverting amplifier with a gain of 26 dB
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.
