Abstract
An example sensing system includes a non-contact sensing electrode configured to sense an electric potential and provide a sensor signal at an output of the sensing electrode based on the sensed electric potential. The output of the sensing electrode is coupled to a first input of an amplifier. The amplifier is configured to provide an amplified output signal representative of at least one measured biosignal based on the sensor signal and a feedback signal provided to the second input of the amplifier. A compensation signal generator is coupled between the output of the amplifier and the second input. The compensation signal generator is configured to estimate corresponding noise and provide the feedback signal to include a filtered signal representative of the estimated noise to the second input to the corresponding noise at the first input of the amplifier and mitigate saturation of the amplifier.
