You have a two-stage amplifier with stage gains of 10 and 5. If stage 1 is poorly biased affecting its gain to 7, how do you recalculate the overall gain?
💡 Hint: Recalculate by considering the adjusted gain of stage 1.
Design a cascaded two-stage RC coupled amplifier where each stage has a target voltage gain of 10 but you find the output of stage 1 is not reaching target due to coupling capacitor impedance. How might you address this?
💡 Hint: Consider the impact of capacitive reactance on gain at operational frequency.
