摘要： An active balun device is provided. The active balun device includes: a differential input portion for receiving an external single input signal to output two complementary differential signals; and a differential amplifier connected to the differential input portion in cascade to amplify the two differential signals received from the differential input portion. Thus, the active balun device has a sufficient gain and a desired bandwidth in a semiconductor circuit.
