This paper presents an energy-efficient digital front-end processor for digital-intensive polar transmitter architecture working on 60 GHz band in standard 28nm CMOS process. This avoids modulating the supply and also eliminates the need of an additional RF limiter and AM detection circuits in the traditional analog-centric polar transmitter architecture. The design challenges on the digital signal...
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...
