Original Abstract Submitted
An impedance adjusting circuit and an impedance adjusting method for zero quotient (ZQ) calibration. The impedance adjusting circuit includes a reference resistor, a first pull-up impedance generator and a second pull-up impedance generator. The reference resistor is coupled between a first sensing node and a low reference voltage. In a first ZQ calibrating operation, the impedance adjusting circuit connects the first pull-up impedance generator to the first sensing node, and compares a first reference voltage and a sensing voltage on the first sensing node to generate the first calibration signal. In a second ZQ calibrating operation, the impedance adjusting circuit connects the second pull-up impedance generator to the first sensing node, and compares a second reference voltage and the sensing voltage to generate the second calibration signal.
