In this paper, a tapered transformer structure based on a layout optimization technique is proposed, for the first time, for the design of silicon-based radio-frequency integrated circuits (RF ICs). Compared with a standard transformer structure, the proposed one showed improved quality factor ($Q$), coupling coefficient ($k$), and transmission coefficient. A three-dimensional electromagnetic simulation was performed to investigate the current crowding effects and coupling mechanism in transformers. We also developed a frequency-independent equivalent-circuit model to capture the transmission characteristics of the transformers. Good agreement between the simulation and measurement results was demonstrated from 0.1 GHz to 8.5 GHz.
