In this paper we present a contribution to create a VHDL-AMS
radio-frequency component library. Currently, integrated circuit
technology tends to integrate in a sole chip not only mixed signal but
also mixed technology systems, going to a more general definition of
the so called Systems On Chip. A library of RF models would be useful
to model, in a same framework, circuits and systems of different
physical domains, including RF, which will certainly optimise design
process of such systems.
Generally, VHDL-AMS, the analogue and mixed signal extension to IEEE
standard VHDL does not include specific formulation for RF devices or
systems modeling, as it does not support distributed parameters for
simulation or description purposes. However, RF devices can be
modeled by means of more general VHDL-AMS resources, like sentences
including algebraic and trigonometric relations.
