Challenge Problems
Push your limits with advanced challenges
Explain how using a buffer can virtually eliminate gain attenuation while cascading amplifiers.
💡 Hint: Focus on the principles of impedance and load effects.
Given two amplifiers with gains of 12 and 8, and a loading resistance of 3kΩ from the first to the second, calculate the actual output voltage if the first stage outputs 2V.
💡 Hint: Use voltage division principles to apply the loading effect.
