The digital revolution (also known as the third industrial revolution) made a dramatic shift from analog to digital technology and electronics. In a world that seems dominated by digital information processing, one may wonder if there is still room for analog functions. Of course, it is unwise to assume that analog signal processing will go extinct. Without analog devices, circuits, and systems, digital systems would lack the means for interaction with the physical world. And the need for such interfaces is only growing as we are stepping into the fourth industrial revolution. Technologies like autonomous drive and the Internet of Things increasingly require advanced sensors in various physical domains, improvements in radio frequency communication, and new energy harvesting solutions, all essentially based on analog devices, circuits, and systems. In the fast-evolving, socially interconnected world, we are witnessing a seismic shift in the amount of data that needs to be processed in real time. Moving forward, the conventional digital processing, with the separation of data and computing, becomes critically constrained by the energy growth of data movement. This will necessitate breaking the barriers of digital abstractions by shifting information representation from symbolic to physically meaningful quantities and switching from sequential discrete-time to continuous-time dynamics. Most of these efforts to revive analog computing borrow essential ideas from natural analog computing processes. These include, but are not limited to, neuromorphic computing, cellular automata, memcomputing, and Ising model–based systems.
