Abstract :
A novel compact model using pole-residue method for ultra-broadband on-chip transformer is presented. This model possesses several paralleled branches for high-order effects of transformers, and it can be easily extracted using the procedure of vector fitting (VF) written in MATLAB. Meanwhile, the key features of the existing equivalent circuit models have been analyzed. The proposed model reaches high accuracy and fits well with 100 GHz measured S-parameters of an on-chip transformer.
