Abstract :
An all-digital polar transmit (TX) architecture exhibits advantages of low cost, low power, as well as reconfigurability with full usage of digital computational power. The design challenge is the need for continuous innovation to further enhance power efficiency and minimize silicon area while achieving the best-in-class RF performance. The design must also meet the increasing demand of concurrent operation for multi-radio SoC integration. The presented Bluetooth TX demonstrates advancements in this direction with over 30% power and 66% area reduction.
