A 3.2 mA-RX 3.5 mA-TX fully integrated SoC for Bluetooth Low Energy

A fully-integrated system-on-chip (SoC) for Bluetooth Low Energy (BLE) with 3.2 mA RX and 3.5 mA TX current consumption is presented. To achieve both low current consumption and high performance, the SoC employs a sliding-IF architecture that avoids out-of-band-blocking signals, a power management unit with improved efficiency, and techniques to reduce current in core circuits. The SoC achieves RX sensitivity of -93 dBm and maximum output power of 0 dBm. The SoC is in compliance with version 4.2 of the Bluetooth specifications and with the radio regulations of the FCC, ETSI, and ARIB. The SoC achieves the world's lowest current consumption for both RX and TX modes in the published product-level SoCs.
