Abstract
This paper presents for the first time single metal layer step-down on-chip transformer. The design is characterized for VHF and UHF frequency ranges. The prototype is coreless (air core), which is suitable for high frequency operations. The design is fabricated in a standard Metal-MUMPs fabrication process, which offers a single structure layer. The primary inductance of 10.7Â nH and the transformer quality factor of 8.8 have been achieved at 1Â GHz. The coupling coefficient is 0.60 and the efficiency is 76% with matched load at 1Â GHz. The total footprint area of micro-transformer is 0.49Â mm2.
