Abstract
An active balun circuit includes a CG transistor having a source terminal thereof connected to an input terminal and a gate terminal thereof grounded, a CS transistor having a gate terminal thereof connected to the input terminal and a source terminal thereof grounded, an asymmetrical transformer, a first output terminal, and a second output terminal. The asymmetrical transformer includes a primary coil and a secondary coil. The primary coil includes a first inductor connected to the CG transistor and a second inductor connected to the CS transistor. The secondary coil includes a third inductor associated with the first inductor and a fourth inductor associated with the second inductor. The first output terminal outputs a first signal generated at the third inductor, and the second output terminal outputs a second signal generated at the fourth inductor.
