An analytical formula for calculating the mutual inductance of planar transformer has been developed in CMOS technology. The proposed formula can predict different turn ratios between primary and secondary coils. Two on-chip transformers have been measured to verify this formula, the results demonstrate the proposed formula is feasible. Furthermore, the equivalent circuit and the corresponding model are proposed to describe the high frequency behavior. (C) 2007 Elsevier B.V. All rights reserved.
