The purpose of this research project is to revise a previous design of a modular data collection device and to develop a biosignal amplifier for use in EEG research. The primary goals of the device redesign were to address the challenges identified at the conclusion of the previous research and to either reaffirm or update various aspects of the implementation – primarily the main components that make up the device. The amplifier circuitry is designed to provide both amplification of the input signals and preliminary filtering of undesirable noise artifacts caused by common environmental sources. Both the collection device and the amplifier circuit were tested individually to verify their viability. These systems are designed to be implemented as part of a larger system, although the specifics of these systems are left up to the requirements of the desired project. This thesis primarily focuses on the design details of these two components.
