A SATURATION-TOLERANT ELECTROPHYSICAL RECORDING INTERFACE

摘要

Signal recording sensor systems in accordance with embodiments of the invention include sensors capable of sensing and capturing electrophysiological signals in the presence of interference signals, an analog front-end including circuitry configured to record electro-physiological input signals as a voltage, and an analog to digital converter including a voltage-controlled-oscillator configured to convert the recorded analog electrophysiological input signal to a phase output. While such signal recording sensor systems can be used in the recording of biosignals and/or electrophysiological signals generated from living organisms, signal recording sensor systems in accordance with embodiments of the invention are not limited to recording biosignals and/or electrophysiological signals.
