Hello I need to make a VCR (voltaje controlled resistor) with transistors becouse I have to work with high power (beetween 8W-40W). It has to have 4 terminals, 2 for the output resistance, and another 2 for the control. I have been working with some designs with transistors, resistors and a potentiometer (to be replaced by a VCR) that works like a high power variable resistor. The rank of the desing must be 100 ohms to 2k omhs and my desing is far to reach that. I don't have useful documentation. I would like that somebody tell me how to find info or show me some similar desing.
Thanks.
Thanks.
