Hi all,
I am designing a VCO and so I am using a V to I converter and then feed this current to ring oscilator.. Here I require a linear relation between the input voltage and the output current. I tried using a simple transistor with V in Gate and current from Drain. But since i this trans is in saturation I get a non linear (square relation). Also due to huge current requirement (for wide range) I cant operate in linear region. Can anyone help me to design a linear V to I converter..
