Abstract
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 electrophysiological 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.
