This review highlights recent developments in the field of epileptic seizure prediction. We argue that seizure prediction is possible; however, most previous attempts have used data with an insufficient amount of information to solve the problem. The review discusses four methods for gaining more information above standard clinical electrophysiological(More)
Low-power, low-phase noise and small size PLL is a critical component in wearable and implantable medical sensors. A new ultra-low power, low-phase noise and small size ring VCO on 65 nm IBM CMOS technology for use in PLL is introduced in this paper. This VCO operates in the Medical Implant Communication Service (MICS) frequency band. This ring oscillator(More)
In this paper we introduce a wireless transmitter suitable for implanted medical devices (IMDs) and neural prostheses. The transmitter achieves 500 kbps data rate while consuming a peak power of 200 µW from a 1.2 V supply in a 130 nm technology and has an active area of 35 µm by 45 µm. The transmitter works in the Medical Implant Communication Service(More)
An ultra-low-power wireless transmitter for embedded bionic systems is proposed, which achieves 40 pJ/b energy efficiency and delivers 500 kb/s data using the medical implant communication service frequency band (402-405 MHz). It consumes a measured peak power of 200 µW from a 1.2 V supply while occupying an active area of 0.0016 mm(2) in a 130 nm(More)
In this review, biomedical-related wireless miniature devices such as implantable medical devices, neural prostheses, embedded neural systems, and body area network systems are investigated and categorized. The two main subsystems of such designs, the RF subsystem and the energy source subsystem, are studied in detail. Different application classes are(More)
The proposed low-power bandgap reference voltage circuitry is specially designed for a temperature sensor of a retinal prosthesis. Retinal prosthesises have great potential for restoring vision to patients suffering from age related macular degeneration (AMD) and retinitis pigmentosa (RP). Here a circuit is proposed and implemented on 65 nm IBM CMOS(More)
Retinal prostheses have great potential in helping restore vision in patients suffering age-related macular degeneration and retinitis pigmentosa. Power consumption is a major problem for implanted devices. Biomedical implant researchers are investigating suitable low-power architectures for future implant systems. For this reason, the design of ultra-low(More)
