摘要:
There is provided an active balun circuit including: a load circuit unit including a first and a second load; a differential amplifying unit including a first amplifying unit connected to the first load, and a second amplifying unit connected to the second load and forming a differential amplifying unit together with the first amplifying unit, the differential amplifying unit differentially amplifying an input signal, and outputting first and second output signals out-of-phase with each other through first and second output terminals, respectively; a current source connected between a ground and a common connection node of the first and second amplifying units, and maintaining a constant amount of current flowing through the differential amplifying unit; and a compensation amplifying unit amplifying the input signal supplied through the input terminal, transmitting the amplified input signal to the second amplifying unit, and rejecting common mode noise of the differential amplifying unit.
