Difference Amplifier Using an Op Amp 

After finding difficulties in Smith Charts to find Impedance Matching prior to amplification sinyal, I found this the easiest way! THANK YOU SO MUCH GENIUS!

This video has just saved me from an hour of pounding my head on my desk. Thank you so vey much!!!

Very well explained, awesome!

Very Nice Sir. Direct and to the point.

Nicely presented. Thanks!

Hi, using lm311p, on breadboard the output always stays at active low (0.65v). Not getting active high, the output is in the off state, regardless of the differential input. Any help ? MC3302P works same as lm339 ?, any modifications needed?

i was getting really frustrated thank you so much

ok I still don't get how you voltage divider the formula

Can Vs- be GND ( single power supply) ?? ex in LM358 ?? Thank you in advance 🙂
