Abstract

A new modeling methodology for on-chip differential spiral inductors is presented. The presented model consists entirely of frequency-independent circuit elements. An automated extraction technique is presented for determining the circuit elements from two two-port S-parameter measurement data sets. The new method allows for a single model to accurately capture the single-ended and differential operations of the device. The modeling methodology is applied to a sample differential spiral inductor. The extracted model shows excellent accuracy in comparison with device measurements over the frequency range 0.2 to 10.2 GHz.
