To start as soon as possible and for a duration of six months.
Recently, neural activity monitoring has become popular in human health care applications (i.e. Alzheimer treatment, prosthesis controlling). Commonly bio-potential signals like brainwaves and neural activities are recorded periodically for investigating the health. These bio-potential signals fall within a frequency band of subhertz range, highly dominated by flicker noise and DC offset. Moreover, bio-potential signals have very wide voltage amplitude ranging from microvolt to millivolt. This implies strict design constraints on the signal conditioning circuitry for bio-potential signals.
The objective of this thesis is to design a high precision advanced chopper amplifier, which is characterized by low noise power and low offset for processing such bio-potential signals to merge electronics and the neuron for tomorrow's bio-medical applications.
- Study the state-of-art chopper amplifiers and ripples suppression techniques
- Compare different chopper amplifier topologies, and select or propose one which fits best for low power designs
- Design and implement the amplifier, including the digital controller if needed.
- Interest in designing a state-of-art bio-potential signals conditioning circuitry
- Student in microelectronics with good understanding of analog and digital integrated circuit design, and experience in the use of CAD tools (i.e. Cadence)
- Good understanding of amplifier design
- Experience in chopping techniques and bio-signal conditioning preferred but not required.
