For this week’s QSPICE schematic capture, we have a revised version of “Composite LTPMC Amplifier” by frequent audio circuit simulation contributor Michael Kiwanuka, from his “An Analytical Approach to Linear Audio Frequency Power Amplifier Design: Selected Papers,” 4th Edition. The original version is QSPICE Forum Schematic Capture #031 and has THD = 7.76981e-05%(9.83687e-05%) in the simulation. The revised design has THD = 0.000144084%(0.000220194%). Please send any submissions to me at tim.mccune@qorvo.com (Schematic Capture Post #041).
