Systematic Design of EMI-Resilient Negative-Feedback Amplifiers

The information transfer capacity of negative-feedback amplifiers, and electronic circuits in general, is limited by three fundamental limitations being noise, bandwidth, and signal power. Electromagnetic Interference (EMI) is not a fundamental limitation, but it also hampers the information transfer. EMI may have such detrimental effects that...
