Abstract
An electronic device capable of bandwidth compensation includes a register unit for storing a calibration code determined by performing an on-die termination (ODT) calibration process and a data receiving circuit, wherein the calibration code is utilized for controlling a termination resistance of an ODT unit. The data receiving circuit comprises a first control circuit coupled to the register unit and the active low-pass filter for generating a first control signal according to the calibration code stored in the register unit, the first control signal being utilized for adjusting a capacitance of a first feedback capacitor unit or a resistance of a first feedback resistor unit of an active low-pass filter.
