Discussion about 'Discussion on a Circuit Including Ideal Operational Amplifier'
Tian Liang · Journal of Electrical & Electronic Education · 2007
This paper points out what and why of the incorrect analysis for voltage followers in reference[1].Negative feedback is introduced in the voltage follower whose output voltage can follow its input voltage.It will work in saturated region if the negative feedback is exchanged into positive feedback and then the circuit is not a voltage follower,but changed into a Schmitt trigger actually.It is noted that the results produced from the circuit simulation software reflect the operation of actual circuits approximately and can not consistent with each other in all cases.
