| Popis: | A WiFi (IEEE 802.11g) and BLE combo transmitter (TX) for IoT applications is presented. A wideband digital polar architecture consisting of an all-digital PLL-based frequency modulator and a switched-capacitor digitally-controlled PA achieves optimal energy efficiency for both WiFi and BLE. The dynamic FM correction and AM alias suppression techniques are applied to support 20MHz 802.11g. Implemented in 28nm CMOS technology with 0.9V supply, this highly reconfigurable TX achieves -22dB EVM for 802.11g up to MCS4 and 1.6% FSK error for BLE. The transmitter only occupies 0.65 mm2 and consumes 27mW and 15mW with OdBm output power for WiFi and BLE, respectively. It results in an excellent energy efficiency of 0.62nJ/b. © 2018 IEEE. |
