If R1=∞ or Rf=0 is set in a common-mode amplifier, it becomes a unity-gain amplifier, or a voltage follower. As a voltage amplifier, its gain is only 1. However, its specialty is that it acts as an im
I just saw a question about JLINK raised by a netizen. I think this document may be helpful to you.
Nice to meet you all.[[i]This post was last edited by desk1983 on 2011-4-15 21:28[/i]]
I would like to ask, I use LM393 to form a zero-crossing comparator, the "-" end is grounded, and the power supply is a unipolar +5V power supply. Then can the "+" end input a voltage signal with a pe
