Abstract

We investigate the energy cost of negative feedback in first and second order linear systems. Previous work demonstrated that, in noisy physical channels, trade-offs between information and power lead to an energy cost for information. In this paper we show that, for a fixed signal power and output noise, the introduction of negative feedback reduces capacity for first and second order lowpass linear systems. This capacity reduction constitutes a fundamental energy cost associated with the use of feedback in linear systems.
