Abstract
An impedance circuit includes a poly-resistor and a controller. The poly-resistor has a first terminal and a second terminal. The controller generates a first control voltage and a second control voltage. The resistance between the first terminal and the second terminal of the poly-resistor is determined according to the first control voltage and the second control voltage. The second control voltage is different from the first control voltage. The proposed impedance circuit can improve the linearity of the poly-resistor.
