Use the Negative Feedback Theory in IC Design
Rong Hu, Xiao Yin Zhang · Advanced materials research · 2013
In this paper, at first, a conceptual circuit is introduced to illuminate how to use negative feedback to set up operating points. After that, a bias circuit is design using negative feedback theory. The stimulated results show that the designed bias circuit are very stable, having a phase margin of 93.04 degrees , and that the output impedance of the bias circuits has a low pass nature with a DC value of about 5 ohms.
