In: Proceddings of the 38th European Microwave Conference. Amsterdam: IEEE, 2008.978-2-87487-006-4http://hdl.handle.net/10400.8/65With the advent of wireless transceiver reconfigurability, a need has been felt to take profit of digital signal processing tools, this way increasing RF circuits’ complexity and heterogeneity. Having this objective in mind, this paper presents an analytical formulation and a novel numerical method for simulating, in a very efficient way, strongly nonlinear heterogeneous RF circuits running in three different time-scales. In order to reduce the computational workload, a new multi-line double multi-rate shooting technique is proposed to operate within a multi-dimensional warped time framework. Obtained results of an illustrative circuit, reveal significant advantages in speed over previous methods recently proposed for the simulation of the same category of circuits.engNonlinear circuitsconference object
