A calibrating system for automatically eliminating or reducing imbalance between a first signal and a second signal is disclosed. The calibrating system includes: a programmable delay module, receiving to the first and the second signals; a phase detecting module, coupled to the programmable delay module, for receiving the first and the second signals from the programmable delay module, and comparing a phase of a reference signal with phases of the first and the second signals, respectively; and a de-skew controlling module, coupled to the programmable delay module and the phase detecting module, for controlling the programmable delay module to eliminate imbalance between the first and the second signals by at least delaying the first signal according to a comparison result of the phase detecting module.
