Abstract :
This work proposes a transformer structure with high-coupling, and small chip area characteristics using current silicon-based technology. The proposed device has tight coupling (k = 0.92), and minimum chip area (O.D. =140 mum) characteristics. In order to understand this device operation in high frequency, an equivalent circuit is developed to extract the model parameters. Based on the proposed transformer in this work, this device is helpful in designing RF integrated circuits for system-on-a-chip applications
