Abstract(s)
With 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.
