Abstract – Implantable medical devices are a rapidly growing area of technology. Invivo monitoring and treatment of key biological parameters can greatly assist in managing health and preventing disease. This talk will focus on innovative solutions to deliver power wirelessly to a greater range of implanted devices including choice of optimal frequency, adaptive matching, high efficiency rectifier design and implant location estimation. We will also discuss innovations in ADC design for implantable devices to minimize power consumption including dynamic resolution adaptation and capacitor array reconfiguration to overcome mismatch limitations. Application to neural sensing will be also discussed.

Dr. Stephen O'Driscoll is a professor at UC Davis and a Visiting Scientist at Google[x]. He received his B.E. degree in Electrical Engineering in 2001 from University College Cork, Ireland and the M.S. and PhD degrees in Electrical Engineering in 2005 and 2009 from Stanford University. He was an Analog IC Designer at Cypress Semiconductor, San Jose from 2001 to 2003 where he worked on clock and data recovery PLLs. During 1999 and 2000 he worked as microwave circuit designer at Farran Technology, Ireland. His research focuses on low power analog and RF IC design with emphasis on biomedical applications.
