Abstract :
A compact model is presented for on-chip differential transformers fabricated in RF CMOS technology on lossy substrates. The model is scalable, derived from the designed physical layout and processing technology. It suffices for transformers´ simulation and synthesis. A new method for calculation of self and mutual inductances of differential transformers is provided. EM-simulation is used to verify the new compact model and results show excellent agreement with the proposed model over a large frequency range (up to 30GHz)
