The proposed fully-integrated digital-intensive TRX SoC allows dual-mode protocols of BLE 5.0 and IEEE 802.14.5 with extended-range wireless connectivity and simple ad-hoc mesh networks for the IoTs in smart homes. A 1.04 - 4V with dual-mode supply schemes enables the SoC to be applied for various IoT systems energy-effectively and extends battery lifetime cost-effectively. The TRX employs a low insertion loss CMOS transmit- receive switch, a class-D power amplifier with HD2 calibration, a low-IF RX architecture with ΔΣ ADC-based complex filter, and a low power ADPLL with LMS-based two-point direct frequency modulation. The TRX implemented in a 28nm CMOS process achieves the maximum output power of +10dBm while consuming 45mW at the TX |
