Wireless biosensors are playing a pivotal role in health monitoring, disease detection and management. The development of wireless biosensor nodes and networks strongly relies on the design of novel low-power, low-cost and flexible CMOS sensor readouts. This brief presents a CMOS ...
Wireless data telemetry for implantable medical devices (IMDs) has, in general, been limited to a few Mbps, and used for applications such as transmitting recordings from an implanted monitoring device, or uploading commands to an implanted stimulator. However, modern neural inte ...
The original paper entitled "Practical Inductive Link Design for Biomedical Wireless Power Transfer: A Tutorial" [1], aimed to provide an accessible review and guide, describing the necessary steps for designing effective biomedical inductive links, without the need for FEM Softw ...
Short-range, low-power, high data-rate telemetry is an increasingly desirable feature for implantable medical devices (IMDs), and is commonly implemented using an inductive link. Pulse Harmonic Modulation (PHM) provides the desired high data rates and low power consumption, but r ...
Point-of-care (PoC) diagnostics rely on the design of low-power and miniaturized readout units that can offer rapid and accurate test results, replacing the need for specialized equipment. CMOS technology can be exploited in order to design complex systems while achieving high en ...
There is growing demand for circuits that can provide ever greater performance from a minimal power budget. Example applications include wireless sensor nodes, mobile devices, and biomedical implants. High speed clock circuits are an integral part of such systems, playing roles s ...
Wireless sensing systems are becoming popular in a range of applications, particularly in the case of biomedical circuits and food monitoring systems. A typical wireless sensing system, however, may require considerable complexity to perform the necessary analog to digital conver ...
Wireless power transfer systems, particularly those based on inductive coupling, provide an increasingly attractive method to safely deliver power to biomedical implants. Although there exists a large body of literature describing the design of inductive links, it generally focus ...

An implantable wireless multi-channel neural prosthesis for epidural stimulation

A fully implantable multi-channel neural prosthesis for epidural stimulation will be demonstrated. The prosthesis features three telemetry-operated independent stimulators providing in total eighteen stimulation channels. The stimulator circuits were implemented in a 0.6-μm CMOS ...
