ABSTRACT:
The present invention relates to a hybrid balun apparatus and a receiver thereof. The hybrid balun apparatus comprises a passive unit, a first active unit, and a second active unit. The passive unit receives an input signal, and outputs an in-phase signal having an identical phase compared to the input signal and an inverse-phase signal having an inverse phase compared to the input signal. The first active unit compensates the in-phase signal of the passive unit corresponding to the input signal. The second active unit compensates the in-phase signal of the passive unit in response to the input signal.
