Design and systemC-AMS modeling of a parallel direct digital synthesizer

This paper presents a new parallel direct digital frequency synthesis (pdds) circuit providing simultaneous multichannel. the proposed circuit has several applications in instrumentation,identification and data communications. after analysis of a set of design architectures and their limitations,we opted for a rapid and optimized architecture using wave arithmetic unit (wau) to operate in a largest frequency range. the effectiveness of our proposed circuit is demonstrated by a high-level design of digital blocks in systemc and analog blocks in sytsemc-ams language. finally,the analysis of result responses of all modules confirms the correct pdds performances for an open microelectronic integration technology.
