gate delay
21Logical effort — The method of logical effort, a term coined by Ivan Sutherland and Robert Sproull in 1991, is a straightforward technique used to estimate delay in a CMOS circuit. Used properly, it can aid in selection of gates for a given function (including… …
22Ring oscillator — A ring oscillator is a device composed of an odd number of NOT gates whose output oscillates between two voltage levels, representing true and false . The NOT gates, or inverters, are attached in a chain; the output of the last inverter is fed… …
23Carry look-ahead adder — A carry look ahead adder is a type of adder used in digital logic. It can be contrasted with the simpler, but usually slower, ripple carry adder ( see adder for detail on ripple carry adders ). A ripple carry adder works in the same way as pencil …
24Carry-lookahead adder — 4 bit adder with carry lookahead A carry lookahead adder (CLA) is a type of adder used in digital logic. A carry lookahead adder improves speed by reducing the amount of time required to determine carry bits. It can be contrasted with the simpler …
25Roland System 100m — The Roland System 100m was a modular synthesizer made in Japan by Roland. It is not to be confused with the Roland System 100 which was an older semi modular Roland synthesizer. Modules *110 VCO/VCF/VCA *112 Dual VCO *121 Dual VCF *130 Dual VCA… …
26Multigate device — A multigate device or multiple gate field effect transistor(MuGFET) refers to a MOSFET which incorporates more than one gate into a single device. The multiple gates may be controlled by a single gate electrode, wherein the multiple gate surfaces …
27Canonical form (Boolean algebra) — In Boolean algebra, any Boolean function can be expressed in a canonical form using the dual concepts of minterms and maxterms. Minterms are called products because they are the logical AND of a set of variables, and maxterms are called sums… …
28Adder (electronics) — In electronics, an adder or summer is a digital circuit that performs addition of numbers.In modern computers adders reside in the arithmetic logic unit (ALU) where other operations are performed.Although adders can be constructed for many… …
29Carry select adder — In electronics, an adder is a combinatorial or sequential logic element which computes the n bit sum of two n bit numbers. The carry select adder is simple but rather fast, having a gate level depth of O(sqrt n).The Carry select adder generally… …
30Wallace tree — A Wallace tree is an efficient hardware implementation of a digital circuit that multiplies two integers.The Wallace tree has three steps: # Multiply (that is AND) each bit of one of the arguments, by each bit of the other, yielding n^2 results.… …
