In this work, a proposed on-chip radio-frequency (RF) transformer design and layout technique is presented to achieve high magnetic coupling coefficient and low insertion loss by segmenting and interleaving wide primary and secondary metal traces.

Additional advantage of such technique is the mitigation of proximity effect and current crowding.

The proposed technique is verified and tested for a square transformer, with different segmentation structures, using EMSight simulator of Microwave Office 2007 (version 7.5) RF / Microwave software tools.

By using this design and layout technique, the magnetic coupling coefficient improves from 0.49 to over 0.72 and lowers the minimum insertion loss from 1.56dB to 1.18 dB at 4.5 GHz center frequency.
