Emerging wireless sensor networks (WSN), wireless personal area networks (WPAN), wireless body sensor network (WBAN) are the key components of Internet of Things(IoT), bringing high demand for ultra-low power, low-cost and high performance transceivers. Conventional transceivers are often designed with low power-efficiency, low flexibility and high cost, which limits their deployment of emerging applications. This research program will focus on design techniques for ultra-low power, low-cost, flexible and reliable receivers for wireless microsystems. To achieve this target, injection lock techniques will be explored and used in a variety of ways. These techniques provide two distinct benefits: a) The use of injection-locked to demodulate ASK/FSK/PSK signals leads to simple non-coherent architecture for the receiver, which is important for low power consumption; b) The unique characteristics of injection locked oscillators offers both flexibility and reliability for the receiver. This program will focus on two main topics; 1) The study of injection-locked oscillators. Systematic and in-depth analysis will be performed. The types of oscillator, the configuration of the circuits and the characteristics of the incident signal will be explored with regard to their effects on locking range. The special application of injection-locked oscillators for chirped signals will also be investigated. The outcome of this topic will be both a theoretical advancement, and the foundation for the subsequent design phase. 2) The design techniques for flexible and reliable receivers. In this part, novel receivers will be designed and validated through circuit simulation tools and lab measurements. The wide locking range of the oscillator is the key building block in the development of these circuits, leading to low power requirements and high performance. The performance of the receiver will be examined with respect to power consumption, data rate, noise and linearity. Finally, this research program will provide excellent training opportunities and a multi-disciplinary research environment in which students will obtain knowledge and skills for future academic and industrial research in low-power circuit design.

新兴的无线传感器网络（WSN），无线个人区域网络（WPAN），无线身体传感器网络（WBAN）是物联网（IoT）的关键组成部分（IoT），对超低功率，低成本和高性能传递者的需求很高。常规收发器通常以低功率效率，低灵活性和高成本设计，这限制了他们在新兴应用程序中的部署。 该研究计划将着重于无线微系统的超低功率，低成本，灵活和可靠的接收器的设计技术。为了实现这一目标，将以各种方式探索和使用注射锁技术。这些技术提供了两个独特的好处：a）使用锁定的注射锁来解调ask/fsk/psk信号导致接收器简单的非固定体系结构，这对于低功率消耗很重要； b）注射锁定振荡器的独特特征为接收器提供了灵活性和可靠性。 该计划将重点介绍两个主要主题。 1）注射锁定振荡器的研究。将进行系统和深入分析。振荡器的类型，电路的配置和事件信号的特性将在其对锁定范围的影响方面进行探索。还将研究注射锁定振荡器在chired信号中的特殊应用。该主题的结果将是理论上的进步，也是后续设计阶段的基础。 2）灵活和可靠接收器的设计技术。在这一部分中，新颖的接收器将通过电路模拟工具和实验室测量设计和验证。振荡器的宽锁定范围是这些电路开发的关键构建块，导致低功率要求和高性能。接收器的性能将在功耗，数据速率，噪声和线性方面进行检查。 最后，该研究计划将提供出色的培训机会和多学科研究环境，在该环境中，学生将在低功率电路设计中获得未来学术和工业研究的知识和技能。
