QSPICE Forum Schematic Capture " Secondary Minor Feedback Loop Response"

[mccunets]

For this week’s QSPICE schematic capture, we have “Secondary Minor Feedback Loop Response” by frequent audio circuit simulation contributor Michael Kiwanuka, from his “An Analytical Approach to Linear Audio Frequency Power Amplifier Design: Selected Papers,” 4th Edition. Please send any submissions to me at tim.mccune@qorvo.com (Schematic Capture Post #0018).
