Here’s this week’s schematic capture, by our friend and frequent audio circuit simulation contributor Michael Kiwanuka. This is from his “An Analytical Approach to Linear Audio Frequency Power Amplifier Design: Selected Papers”, 4th Edition, by Michael Kiwanuka. “This triple composite nested negative feedback arrangement allows this audio power amplifier with a common-emitter output stage to perform better than the best non-composite, non-error-corrected audio power amplifiers with emitter-follower output stages in respect of linearity and output impedance.” Please send any submissions to me at tim.mccune@qorvo.com (Schematic Capture Post #066)
