A alphacat New Member Jan 30, 2010 #1 Is there any configuration of an Op Amp (with feedback), that would give a gain equal to the ratio of two resistors - say R1/R2? (polarity doesnt matter). Thank you. Last edited: Jan 30, 2010

P pankhuri01 New Member Jan 30, 2010 #2 yes. finite impedance amplifier. you must have read about voltage controlled voltage source.,in that if you ground v1. you will get it! Last edited: Jan 30, 2010

Vizier87 Active Member Jan 30, 2010 #6 The datasheets of op-amps like LM358 also give out excellent schematics, I learnt that the hard way.
J jcircuited New Member Jan 30, 2010 #7 hi there its easy i think. just need to use the op amp as an inverting amp ,ie input to the negetive terminal the gain will be -R1/R2

P pankhuri01 New Member Feb 7, 2010 #8 there is non inverting amplifier,look for that! https://www.electro-tech-online.com/custompdfs/2010/02/btech_electronics_and_communication.pdf go and see this there r various types of amplifier and u will find urs! Last edited: Feb 7, 2010
