Resumo(s)
This paper describes a new time-domain simulation
method particularly amenable for highly heterogeneous
nonlinear RF circuits as modern wireless transceivers that
combine analog RF and both analog and digital base-band
circuitry. It uses innovative multi-rate Runge-Kutta algorithms
applied to the envelope transient method over a time-domain
periodic steady-state technique (shooting), to efficiently resolve
strongly nonlinear circuits excited by forcing functions of very
distinct time-scales and exhibiting slow (latent) and fast-varying
(active) state-variables. Attributing different time-steps to these
latent and active state-variables speedup gains of more than 1-to-
7 in simulation time were obtained for even a circuit example of
very small size.
