Samenvatting

This work presents a fully-integrated sub-GHz radio System on Chip (SoC) for Low-Power Wide-Area Networks (LPWAN) and Internet of Things (IoT) applications. The receiver (RX) achieves 77dB blocker rejection and -106dBm sensitivity at 50kbps. The transmitter (TX) features a Switched-Capacitor Power Amplifier (SCPA) that delivers 13.5dBm output power. To fulfil stringent Japanese emission regulation, a novel digitally time-dithered SCPA ramping technique is proposed. The presented RX and TX consume 8mW and 113mW, respectively, from a supply as low as 1.2V.
