Abstract

Since it was introduced in the ‘90s, CMOS technology has brought an important improvement to modern electronics, being significantly suitable for the progressive development of ICs in terms of area, number of transistors per chip and channel length. As predicted by Moore’s laws in the ‘70s, the evolution of these features has followed an exponential trend until now. However, this development curve is expected to encounter a saturation soon: in a few years, it will not be possible to scale down devices and raise the number of transistors per chip at the current rate, due to significant short-channel effects (related to the reduced dimensions of the devices) that negatively influence their performances.

This technological limit led to the exploration of innovative approaches that could overcome the problem, essentially divided in two main categories: the “More than Moore” approach, which exploits the existing CMOS technology to integrate devices belonging to different domains on the same SoC (System-on-Chip), and the “Beyond CMOS” approach, which considers alternative technologies able to overcome the standard CMOS limits and, at the same time, to realize a logic that works the same way
