Abstract: This talk overviews the motivation, challenges and solutions of realizing energy-harvesting Bluetooth Low-Energy (BLE) receiver and transmitter in 28-nm CMOS; both are the cornerstones of energy-autonomous IoT radios. A fully-integrated micropower manager is proposed to customize the internal supplies and bias voltages to balance the active performance and sleep power. Novel circuit techniques enabling sub-0.3V operation are introduced for the low-noise amplifier (LNA), mixers, voltage-controlled oscillator (VCO), phased-locked loop (PLL) and power amplifier (PA).
Biography:Pui-In (Elvis) Mak received the Ph.D. degree from University of Macau (UM), Macao, China, in 2006.
