Low-power SoC design techniques for Bluetooth/Bluetooth Low Energy

Bluetooth and Bluetooth Low Energy are one of the most popular wireless standards for short range communications. One of the key features is low power operation to minimize form factor of sensor nodes including battery in the Internet-of-Things (IoT) era. Our latest Bluetooth Low Energy SoC achieves -92 dBm receiver sensitivity with 6.3 mA peak current consumption. Transmitter maximum output power is 0 dBm. Transceiver architecture together with analog and digital circuit techniques and power management techniques are discussed.
