Abstract :
Lumped elements are considered as very attractive structures for the realisation of MMICs with respect to considerable size-reduction. Improved models for integrable lumped-element straight-line, single-loop, and spiral inductors, as well as for interdigitated and MIM capacitors, have been derived using numerical solutions of the inductance integral, basic microstrip theory, and network analysis. The broad experimental verification shows good agreement between models and experiments, with deviations of 5-10% up to 18 GHz. Besides the practical values and frequency range, losses of the lumped elements are presented
