Abstract
Ultra-low-power (ULP) radios are the key element of a wide variety of Internet-of-Things (IoT) products. This lecture discusses the pros and cons of different state-of-the-art ULP RF techniques such as current-reuse, function-reuse and ultra-low-voltage. Toward self-powering by the environments, the opportunity of using energy-harvesting sources such as thermal, light and vibration will also be presented. State-of-the-art industrial radios will serve as the basis to underline the current achievements and project the future challenges.

Title
High Performance Hybrid ADCs & Digital  Assisted Techniques

Abstract
SAR ADCs achieve excellent power efficiency due to its simple architecture and dynamic operation, while its conversion speed is limited by its sequential conversion. Hybrid ADC takes the design advantages of multi conventional ADC architecture to optimize the conversion speed, resolution and power dissipation. This talk introduce a hybrid ADC architecture combining the flash, SAR and pipelined ADC with interleaving and op-amp sharing schemes to achieve near GHz sampling rate and 11 bit resolution. Moreover, some digital assisted solutions are also introduced that fix the conversion errors from offset, reference and nonlinearity from DAC.
