MIMO Switched-Capacitor converter using only parasitic capacitance with Scalable Parasitic Charge Redistribution

ESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference, 2016
In this work a Multiple-Input Multiple-Output (MIMO) Switched-Capacitor (SC) converter is presented that generates Multiple DC voltages using only the parasitic capacitances already present in fully-integrated SC converters. In combination with the Scalable Parasitic Charge Redistribution technique, the presented MIMO converter can provide voltage ...

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

Advanced Materials Technologies, EarlyView.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...
