Abstract
This paper presents an energy-efficient digital signal processor (DSP) for rectangular-to-polar conversion in 802.11ad polar transmitter working on 60 GHz band. Firstly, system simulations with a complete transmission chain are conducted with regard to error vector magnitude and output spectrum, which allows to systematically optimize the design requirements on the DSP block. Secondly, algorithm and architecture co-optimization on the DSP block is explored to minimize the power consumption. Finally, the proposed DSP is synthesized using 28 nm CMOS technology, which provides a throughput of 7.04 Giga samples per second with a power consumption of 28 mW, and area of 0.01 mm2.Keywords
