In near-field electromagnetic links, the inductive voltage is usually much larger than the compliance of low-voltage integrated-circuit (IC) technologies used for the implementation of implantable devices. Thus most integrated power-recovery approaches limit the induced signal to low voltages with inefficient shunt regulation or voltage clipping. In this(More)
Spinal cord injury (SCI) is one of the most complex and devastating medical conditions. Its worldwide incidence ranges from 11 to 112 per 100,000 Population (Blumer & Quine, 1995; DeVivo, 1997). SCI leads to different degrees of dysfunction of the lower urinary tract due to a large variety of possible lesions. Immediately after SCI, flaccid paralysis sets(More)
In order to investigate new neurostimulation strategies for micturition recovery in spinal cord injured patients, custom implantable stimulators are required to carry-on chronic animal experiments. However, higher integration of the neurostimulator becomes increasingly necessary for miniaturization purposes, power consumption reduction, and for increasing(More)
In this paper, we present low-power circuit techniques for implementing a closed-loop neurostimulator (CLNS) as an alternative treatment for medically refractory epilepsy. The proposed circuit has low-power dissipation with better detection sensitivity compared to the recently proposed circuit techniques for epileptic seizure detector. We demonstrate(More)
