| Abstract: | An improved lumped-element equivalent circuit model of spiral inductors on GaAs substrates is developed in this paper, which can provide a good simulation of the actual high-frequency effect for the on-chip spiral inductor. Based on the electromagnetic full-wave method, spiral inductors with different geometry parameters are simulated and analyzed. The effective inductor, Q-factor and the self-resonant frequency are extracted from S-parameters. Using the parameter optimization and curve fitting, the analytical formulations are given for all elements on the circuit model. Such formulations can be used in the RFIC and MMIC design, which will improve the design efficiency tremendously. |
