Hi plz this question
Design an inverting amplifier to provide a closed-loop voltage gain of Ay = -22 V/V. The maximum input voltage signal is 30 mV with a source resistance in the range of 1 kls R, < 3 kN. The variable source resistance should introduce a difference in the gain no more than a 2% of the gain factor. What is the range in output voltage?
