Hi,
I need help in designing a transconductance stage. The problem I am facing is that the load of the transconductance stage is very small ~ 20 ohms and i need to drive it with current ~ 50mA.
A transconductance stage has high output impedance so how do i drive a small load without loading it???
Also coud someone point me to circuit topologies??
I need some advice really fast..
Pls help

Just to add to my previous post.
So basically I need to design a current source (transconductance stage) and must be linear across the input common voltage range...
