Cascade configuration

Definition

A cascade configuration is a setup in which multiple molecular logic gates are connected in series to perform complex logical operations. This arrangement allows the output of one gate to serve as the input to another, enabling a higher degree of computation and functionality in molecular systems. By linking gates together in this manner, cascade configurations can execute multi-step logic operations, effectively expanding the capabilities of molecular electronics.
