Hi there,
i am trying to design a 10-bit binary weighted resistor ladder, the ladder is switch controlled, and can get binary weighted values from R, 2R, 4R,..... 512R. And it can be sumed based on a SAR logic control. Is there such a ladder? I just want from two node, I can get different resistance which can be tuned based on a SAR logic. It look like a parallel connected switch controlled cap array.
Any ideas?
Thanks
