A CMOS IC for portable EEG acquisition systems

A Low-Power CMOS Chopper Amplifier for EEG Acquisition Systems

T demand for technologies that help neuroscientists and clinicians to actively observe a large number of neurons in the brain has increased significantly. Currently the biopotential acquisition systems are bulky and not portable that makes it difficult for the on-going diagnostics and causes discomfort to the patient. There is a need to make these systems more compact and to extend their applic...

Draft 2: A Low Power CMOS Chopper Amplifier for EEG Acquisition Systems

طراحی و ساخت یک سیستم تشخیص خواب آلودگی راننده مبتنی بر پردازش‌گر سیگنال TMS320C5509A

Every year, many people lose their lives in road traffic accidents while driving vehicles throughout the world. Providing secure driving conditions highly reduces road traffic accidents and their associated death rates. Fatigue and drowsiness are two major causes of death in these accidents; therefore, early detection of driver drowsiness can greatly reduce such accidents. Results of NTSB inves...

A Wireless EEG Acquisition System with Thermoelectric Scavenging Microdevice

This paper presents a wireless EEG acquisition system powered by a thermoelectric energy scavenger, which was optimised to convert the small thermal power available in the human-body. The wireless EEG system is composed with up to four EEG electrodes. A radio-frequency (RF) transceiver for operation in the 2.4 GHz ISM band, was optimised and fabricated in the UMC RF 0.18 μm CMOS process. The re...

Compressive image acquisition in modern CMOS IC design

Compressive sampling (CS) offers bandwidth, power, and memory size reduction compared to conventional (Nyquist) sampling. These are very attractive features for the design of modern complementary metal-oxide semiconductor (CMOS) image sensors, cameras, and camera systems. However, very few integrated circuit (IC) designs based on CS exist because of the missing link between the well-established...
