Abstract
In one example, a method of compensating resistance in an integrated circuit includes providing a four terminal resistor in a semiconductor substrate. The resistor includes a first resistor and a second resistor coupled in series, a first terminal at a first end of the resistor, a second terminal at a second end of the resistor, a test terminal at a node connecting the first resistor and the second resistor, and a tuning terminal. The first resistor has a first conductivity type and the second resistor has a second conductivity type opposite to the first conductivity type. The first resistor includes a first portion extending along a first direction and a second portion extending along a second direction perpendicular to the first direction. The method further includes computing a voltage to be applied at the tuning terminal to compensate the difference between the resistance of the first and the second resistors.
