Modified Current Feedback vs Voltage Feedback Signals Distortion Effect

In this paper, the modified circuit signals distortion effects of feedback current in comparison with the voltage feedback were discussed. The result from comparison circuit is the current feedback affects high signals distortion and independent of the internal components as the voltage feedback. The objective of this modification is to improve high signal distortions. The comparison of a harmonic signal output (THD: 58.33% load 10k Ω ) with a frequency response well to 9.36MHz and display simulated by the OrCAD PSpice.
