提出了一款用于无线传感器网络的多标准极坐标发射机，支持2.3/2.4GHz频段的IEEE802.15.6、Zigbee和BLE标准。采用90nm CMOS工艺实现，能效为2.7nJ/b，解决了传统发射机功耗过高的问题。
3/2.4GHz multi-standard transmitter (TX) for wireless sensor networks and wireless body area networks. Several 2.3/2.4GHz wireless standards have been proposed for such applications, including IEEE802.15.6 (BAN) for body area networks, IEEE802.15.4 (Zigbee) and Bluetooth Low Energy (BLE) for sensor networks and IEEE802.15.4g (SUN) for smart buildings. Recent standard compliant shortrange TXs [1-6] typically consume DC power in the range of 20 to 50mW. This is rather high for autonomous systems with limited battery energy. Implemented in a 90nm CMOS technology, the presented TX saves at least 75% of power consumption by replacing several power-hungry analog blocks with the digitallyassisted circuits. This TX is compliant with all 4 of these standards, while dissipating only 4.5mA from a 1.2V supply.
