Journal ArticleDOI
Practical Inductive Link Design for Biomedical Wireless Power Transfer: A Tutorial
TL;DR: This tutorial paper reviews and collects the methods and equations that are required to design an inductive link for biomedical wireless power transfer, with a focus on practicality.
Journal ArticleDOI
An Integrated Implantable Stimulator That is Fail-Safe Without Off-Chip Blocking-Capacitors
TL;DR: A neural stimulator chip with an output stage (electrode driving circuit) that is fail-safe under single-fault conditions without the need for off-chip blocking-capacitors is presented and capacitance reduction to the picofarad range is allowed to be integrated on-chip.
Journal ArticleDOI
Current Conveyor-Based Square/Triangular Waveform Generators With Improved Linearity
TL;DR: Two second-generation current conveyor (CCII+)-based resistance-capacitance (RC) square/triangular waveform generators, which have been derived from their voltage-mode op-amp-based schemes, with independent control of frequency are presented.
Journal ArticleDOI
Design of a low-noise preamplifier for nerve cuff electrode recording
TL;DR: In this article, the authors present the argument for the use of BiCMOS technology in this application and then describe the design and evaluation of a complete preamplifier fabricated in a 0.8-/spl mu/m double-metal double-poly process.
Journal ArticleDOI
