While designing layout of analog circuit, I came across a resistor with three terminals in the schematic. The third terminal was connected to the bulk or the substrate which was in turn biased (vdd or vss). Can anyone explain me why this resistor had three terminals, what is its advantage and what if we have used a simple two terminal resistor instead of this, could this lead to any difference?
