Abstract
A radio frequency input/output circuit with a composite inductor structure is presented. The composite inductor structure has a plurality of inductors that are interwound. The composite inductor structure is implemented on a chip. The plurality of inductors are magnetically coupled. The plurality of inductors are interwound around a core. A second inductor is coupled in series with a first inductor and the first inductor is coupled in series with the third inductor. The first inductor and the third inductor are coupled at a centre tap, such that the first inductor and the third inductor form a centre-tapped coil. The centre tap is coupled to an input terminal.
