Design and SystemC-AMS Modeling of a Parallel Direct Digital Synthesizer

Abstract

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.
