Hello, I have this problem: design a circuit using diodes, resistors and voltage sources to obtain the input function. And the input function is Iin vs Vin plot with following points connected as straight lines: (2V,0mA), (3V,2mA), (4V,6mA). I guess I need a hint on what kind of topology this might be and also, would I use several voltage sources? Anyway.... i need some help seeing to start this problem. Thanks in advance.
