Abstract: A biosignal apparatus is described including an amplifier and a sampler. The amplifier is configured to alternate between an operating state and a low power state based on a periodically changing control signal. The sampler is configured to sample a signal output from the amplifier in response to the amplifier being in the operating state and maintain the sampled signal in response to the amplifier being in the low power state.
