The suffix 'omics' has been added to the names of many fields to denote studies undertaken on a large scale. Threshold science has become so pervasive in everyday life of making decisions. This paper provides a brief introduction and review to the emerging field of Threshnomics by explaining the threshold science applied in various domains. This paper reflects the wide range of threshold applications in algorithms and circuit design and attempt to correlate the threshold notion through neuronal equivalent operator.

“…27(a). The feasibility of such an implementation follows from the fact that any TLF can be represented in a ratio form sgn sgn sgn (2) where is a certain subset of indexes such that . The voltage on node is determined by the ratio of sums of s of pMOS and nMOS transistors.…”

“…The power reduction comes both from having fewer TLGs and from using the new SPD-NTL gates. 2 Finally, a conceptually different implementation was proposed in [155] and [156]. The key computational concept is to use a floating-gate device as a programmable-switched conductance (as in [106] and [107]).…”

This paper is an in-depth review on silicon implementations of threshold logic gates that covers several decades. In this paper, we will mention early MOS threshold logic solutions and detail numerous very-large-scale integration (VLSI) implementations including capacitive (switched capacitor and floating gate with their variations), conductance/current (pseudo-nMOS and output-wired-inverters, including a plethora of solutions evolved from them), as well as many differential solutions. At the end, we will briefly mention other implementations, e.g., based on negative resistance devices and on single electron technologies.

“…Instead, we shall try to cover important types of architectures and present several representative examples. For keeping the paper's length reasonable, the early days of TL implementations (i.e., when the technologies were TTL, ECL, I 2 L, and nMOS), although quite instructive, will not be covered here (the interested reader should consult [1]). …”
