Title: iip3
Post by dg12 on Mar 29^th, 2016, 7:21am

Hello

I need some help regarding the measurement of iip3 for transconductor or an inverter. If I want to use this transconductor in filters what load should I connect at the output to measure the iip3?? If I need a port at the output how can the resistance value be decided??

Regards
Dg

You should load your circuit based on what it will be driving. You need not use a port.

Thanks for the reply... If I'm using a capacitive load, can you elaborate on how to measure iip3 without using port??

I'm afraid I don't have the time. Why don't you just try it. You can report back if you get stuck.
