Developing low-power IoT systems for wearable sensors devices

nandbox Inc.致力于为信息通信平台和物联网（IoT）应用提供创新技术，专注于隐私、安全以及更大的企业与个人/机器通信分组。该公司的路线图包括开发一套完整的物联网模块，应用于家庭自动化和使用nandbox通信消息平台的可穿戴设备。这些物联网设备需要通过模数转换器（ADC）设备与传感器接口，这需要严格的规格，包括非常高的分辨率和超低的功耗。为了超低功耗和成本，有必要使用片上系统（SoC）概念，其中所有模拟前端电路和数字后端信号处理都实现在单个硅芯片中。由于在SoC中为其物联网实现高分辨率ADC的复杂性，nandbox需要帮助研究和开发用于其未来物联网产品的超低功耗高分辨率ADC。本研究项目的目标是研究和设计一种用于物联网应用的高分辨率ADC的新架构，其超低功耗性能小于100微瓦。这些目标包括研究适合物联网应用的现有可用架构，并提供适合nandbox规范的最佳架构的全面研究。提出一种新的ADC架构，克服了在面向数字的SoC技术中实现模拟和混合信号电路的挑战。利用CMOS技术在电路和ADC的布局层面进行设计和实现。制作和测试adc以验证其性能。

nandbox Inc. is delivering innovative technologies for messaging communication platform and Internet ofThings (IoT) applications with focus on privacy, security, and bigger grouping for business toindividual/machine communications.The company roadmap includes development of a complete set of IoT modules applied to home automationand wearable devices using nandbox communication messaging platform. These IoT devices need to interfacewith sensors via analog-to-digital converter (ADC) device that requires stringent specifications including veryhigh resolution and ultra-low power. For an ultra-lower power and cost, it is necessary to use thesystem-on-chip (SoC) concept where all the analog front-end circuits and digital backend signal processing areimplemented into a single silicon chip.Due to the complexity of implementing high resolution ADC in SoC for their IoT, nandbox needs assistance tostudy and develop this ultra-low power high resolution ADC for their future IoT products.The objective of this research project is to study and design a new architecture for high resolution ADC withultra-low power performance less than 100 micro-Watts for IoT applications. These objectives includeresearching the existent available architectures suitable for IoT applications and deliver a comprehensive studyon the best architectures suitable for nandbox specifications. Propose a new ADC architecture that overcomesthe challenges of implementing analog and mixed signal circuits in digital oriented SoC technology. Designand implement at the circuit and the layout levels of the ADC using CMOS technology. Fabricate and test theADC to validate the performance.
