2. Digital electronics - Wikipedia

   The first integrated circuit logic gates cost nearly US$50, which in 2023 would be equivalent to $515. Mass-produced gates on integrated circuits became the least-expensive method to construct digital logic. With the rise of integrated circuits, reducing the absolute number of chips used represented another way to save costs. The goal of a ...

3. Current-mode logic - Wikipedia

   en.wikipedia.org/wiki/Current-mode_logic

   Current mode logic (CML), or source-coupled logic (SCL), is a digital design style used both for logic gates and for board-level digital signaling of digital data. The basic principle of CML is that current from a constant current generator is steered between two alternate paths depending on whether a logic zero or logic one is being represented.

4. Circuit (computer science) - Wikipedia

   en.wikipedia.org/wiki/Circuit_(computer_science)

   Circuits of this kind provide a generalization of Boolean circuits and a mathematical model for digital logic circuits. Circuits are defined by the gates they contain and the values the gates can produce. For example, the values in a Boolean circuit are Boolean values, and the circuit includes conjunction, disjunction, and negation gates.

5. Boolean circuit - Wikipedia

   Example Boolean circuit. The ∧ nodes are AND gates, the ∨ nodes are OR gates, and the ¬ nodes are NOT gates. In computational complexity theory and circuit complexity, a Boolean circuit is a mathematical model for combinational digital logic circuits.

6. Logic gate - Wikipedia

   en.wikipedia.org/wiki/Logic_gate

   Logic gates can be made from quantum mechanical effects, see quantum logic gate. Photonic logic gates use nonlinear optical effects. In principle any method that leads to a gate that is functionally complete (for example, either a NOR or a NAND gate) can be used to make any kind of digital logic circuit. Note that the use of 3-state logic for ...

7. Integrated injection logic - Wikipedia

   en.wikipedia.org/wiki/Integrated_injection_logic

   Integrated injection logic (IIL, I 2 L, or I2L) is a class of digital circuits built with multiple collector bipolar junction transistors (BJT). [1] When introduced it had speed comparable to TTL yet was almost as low power as CMOS , making it ideal for use in VLSI (and larger) integrated circuits .
