Abstract

This talk overviews the motivation, challenges and solutions of realizing ultra-low-voltage Bluetooth Low-Energy (BLE) receiver and transmitter in 28-nm CMOS for energy-autonomous IoT nodes. A fully-integrated micropower manager is introduced to customize the internal supplies and bias voltages to balance the active performance and sleep power of each building block. Novel circuit techniques enabling sub-0.3V operation are proposed for the low-noise amplifier (LNA), mixers, voltage-controlled oscillator (VCO), phased-locked loop (PLL) and power amplifier (PA). Future research directions will also be discussed.
