Book Description
This book presents new circuits and systems for implantable biomedical applications targeting neural recording. The authors describe a system design adapted to conform to the requirements of an epilepsy monitoring system. Throughout the book, these requirements are reflected in terms of implant size, power consumption, and data rate. In addition to theoretical background which explains the relevant technical challenges, the authors provide practical, step-by-step solutions to these problems. Readers will gain understanding of the numerical values in such a system, enabling projections for feasibility of new projects.

Book Description
This book describes new circuits and systems for implantable biomedical applications and explains the design of a batteryless, remotely-powered implantable micro-system, designed for long-term patient monitoring. Following new trends in implantable biomedical applications, the authors demonstrate a system which is capable of efficient, remote powering and reliable data communication. Novel architecture and design methodologies are used to transfer power with a low-power, optimized inductive link and data is transmitted by a reliable communication link. Additionally, an electro-mechanical solution is presented for tracking and monitoring the implantable system, while the patient is mobile.

Book Description
This dissertation presents energy-efficient schemes for short-range wireless communication for wearable devices. Generally, there are two types of wireless scenarios that happen around the human body. The first case is the data transfer between the wearable devices and the local hub devices, e.g., smartphones and smartwatches, allowing to connect to the external network and centrally control multiple wearable devices. Many researchers had proposed various wireless approaches for this scenario; however, there are still limitations in realistic implementations such as restricted form factors and limited energy sources of wearable devices. To address the barriers and challenges of the previously proposed schemes, my doctoral research introduced a new data transmission concept around the human body using magnetic fields, showing the theoretical background and experimental results that validate that the human body acts as a leaky dielectric waveguide. To demonstrate that the proposed concept can be implemented in the practical application, e.g., Hi-Fi audio streaming for portable headphones, this dissertation describes the design procedure and its measurement results of an energy-efficient ultra-low-power transceiver fabricated with CMOS technology. The other wireless scenario occurs in a single wearable device, especially a body sensor device. For the practical reasons of accurate health monitoring, the body sensor device needs to be implanted or injected inside the human body, and it should operate in a fully-wireless environment for the portability of the wearable devices. This work presents guidelines for the design and optimization of on-chip coils used for wireless millimeter-scale integrated neural implants as an example of this wireless scenario. Since available real estate of a silicon chip is limited, on-chip coil design involves difficult managing multi-dimension trade-offs amongst the number of turns, trace width and spacing, proximity to other active circuits and metalization, quality factor, matching network performance/size, and load impedance conditions, all towards achieving high data/power transfer efficiency.

Book Description
Despite tremendous progress over the years, current brain-machine interface (BMI) systems are relatively bulky, highly invasive, and limited in their effectiveness except for highly constrained tasks such as moving a cursor on a computer screen. To improve performance of current BMI systems, it is necessary to dramatically increase spatial resolution and coverage across the brain without constraining the mobility of the subject. This calls for innovative approaches to high-density integrated neural recording and stimulation using non-invasive or minimally invasive microelectrode and custom silicon integrated circuits at extreme energy and area efficiency. In this thesis, I present energy-efficient fully integrated miniaturized implants for electrocortical recording and stimulation, and unobtrusive body-area networks systems for subcutaneous power delivery and data communication, as fundamental building blocks to next generation BMI. First I describe a fully wireless, encapsulated neural interface and acquisition chip (ENIAC) in 180nm silicon-on-insulator (SOI) complementary metal-oxide-semiconductor (CMOS) technology for 16-channel neural recording and stimulation including integrated 4x4 electrode array, coil antenna, and wireless power transfer and data telemetry without any external components, completely contained in less than 3mm3 volume suitable for minimally invasive surgical insertion on the cortical surface. A novel fully integrated wireless power receiver design with an RF-decoupled H-tree signal distribution network delivers 1mW power over 1 cm distance while mitigating RF interference in the sensitive analog front-end and acquisition circuits for recording of electrocorticography (ECoG) signals transmitted through the skull. Second I highlight a 1mm2 16-channel neural recording and acquisition system-on-chip in 65nm CMOS offering 92 dB input dynamic range and
