A '''gate equivalent''' ('''GE''') stands for a unit of measure which allows specifying ''manufacturing-technology-independent complexity'' of [[digital circuit|digital electronic circuits]].<br />
For today's [[CMOS]] technologies, the silicon area of a two-input drive-strength-one [[Negated AND gate|NAND]] [[logic gate|gate]] usually constitutes the ''technology-dependent'' unit area commonly referred to as gate equivalent.<br />
A specification in gate equivalents for a certain circuit reflects a complexity measure, from which a corresponding silicon area can be deduced for a dedicated manufacturing technology.<br />
<br />
In digital circuit design, a dedicated ''[[standard cell]] library'' is employed for each manufacturing technology (e.g., CMOS). The standard cell library comprises many different [[logic gate]]s, for example a NAND gate. For each logical type of logic gate, e.g., a two-input NAND, there usually exist different physical realizations in the standard cell library, for instance with different output drive strengths.<br />
<br />
Basically, a two-input [[drive-strength-one]] NAND gate in CMOS technology consists of four [[transistor]]s. <br />
