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 [1,2,6]. The design challange 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 increaing demand of concurrent operation for multi-radio SoC integration [3,4]. The presented Bluetooth TX demonstrates advancements in this direction with over 30% power and 66% area reduction.
