Asynchronous (clockless or self-timed) sequential logic is not synchronized by a clock signal; the outputs of the circuit change directly in response to changes in inputs. . The advantage of asynchronous logic is that it can be faster than synchronous logic, because the circuit doesn't have to wait for a clock signal to process inp
Switching circuit theory is the mathematical study of the properties of networks of idealized switches. Such networks may be strictly combinational logic, in which their output state is only a function of the present state of their inputs; or may also contain sequential elements, where the present state depends on the present state and past states; in that sense, sequential circuits are said ...
The circuit is guaranteed not to show any output change in response to an input change before t cd time units (calculated for the whole circuit) have passed. The determination of the contamination delay of a combined circuit requires identifying the shortest path of contamination delays from input to output and by adding each t cd time along ...
This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input. In other words, sequential logic has memory while combinational logic does not. Combinational logic is used in computer circuits to perform Boolean algebra on input signals and on stored data. Practical ...
Asynchronous circuit (clockless or self-timed circuit) [1]: Lecture 12 [note 1] [2]: 157–186 is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components.
A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic ...
In theoretical computer science, a circuit is a model of computation in which input values proceed through a sequence of gates, each of which computes a function. 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 ...
[7] Individual circuit components. Finally, the individual circuit components are chosen to carry out each function in the overall design; at this stage, the physical layout and electrical connections of each component are also decided, this layout commonly taking the form of artwork for the production of a printed circuit board or Integrated ...
