Abstract
A device includes a physiological sensor having a plurality of sensing electrodes, and a signal combining chip having a plurality of input channels, a waveform generator, a summing circuit, and an output channel. The plurality of input channels are configured to receive a plurality of voltage signals. Each input channel is configured to receive a respective one of the plurality of voltage signals from a respective one of the plurality of sensing electrodes. The waveform generator is configured to generate a set of modulation signals, each of which modulates a corresponding voltage signal of the plurality of voltage signals to generate a corresponding encoded voltage signal and form a set of encoded voltage signals. The summing circuit is configured to superimpose the set of encoded voltage signals to form a combined voltage signal that is outputted through the output channel.
