how does an operational transconductance amplifier work anyway and what are they used for that op amps can't do
@Felthry benefit of being with my parents is I'm sitting next to my RF/EE dad
he says the main practical difference is that they have different operating characteristics than voltage-voltage op amps, like, they're much faster, which makes them useful in variable frequency radio stuff
on the other hand they don't have negative feedback which other op amps do have which to a first-order approximation means that they have infinite impedence and some other properties determined solely by the resistors around it, and so it's easy to swap out one op amp for another without having to make a lot of changes to your circuit (which is not true for transconductance op amps)
