Summary: 
A fully-integrated system-on-chip (SoC) for Bluetooth Low Energy (BLE) with 3.2mA RX and 3.5mA TX current consumption is presented. To achieve both low current consumption and high performance, the SoC employs a sliding-IF architecture with high tolerance against 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 -93dBm and maximum output power of 0dBm. 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 minimum level of current consumption for both RX and TX modes in the published product-level SoCs.
