A behavioral model of sampled-data systems in the phase-frequency transfer domain for architectural exploration of transceivers

This paper presents a framework for behavioral modeling of transceiver front-ends including sampled-data systems. The operation of the building blocks is described as an interaction in a multi-dimensional space between phases and/or frequencies. This description gives insight in the origin of non-ideal signals suggesting ways to improve the performance of the system. Its main application is the architectural exploration of RF architectures. Both continuous linear systems and sampling operations are mathematically represented by the basic operators of the phase-frequency transfer description: polyphase harmonic transfer matrices and distortion tensors. A Matlab-based implementation of the model demonstrates the usefulness of the model
