Sequential Logic Design

Since 2n is a nite value, sequential circuits are called also nite state machines. We will discuss two types of sequential circuits 1. feedback sequential circuits use ordinary gates and feedback loops to obtain memory in a logic circuit are used to create the building blocks of other sequential circuits, i.e., latches and ip-ops

Sequential circuit is a combinational logic circuit that consists of inputs variable X, logic gates Computational circuit, and output variable Z. The design of sequential circuits can be challenging due to the need to ensure that the timing of the inputs and outputs is correct.

Sequential circuits have higher propagation delay because the input signal passes through multiple stages of logic circuits and memory elements. Sequential circuits are relatively complicated and time taking process to design and analyze. Sequential circuits require a proper synchronization and clock distribution to work as intended.

The word quotSequentialquot means that things happen in a quotsequencequot, one after another and in Sequential Logic circuits, the actual clock signal determines when things will happen next. Simple sequential logic circuits can be constructed from standard Bistable circuits such as Flip-flops, Latches and Counters and which themselves can be made by simply connecting together universal NAND

6. Sequential Logic. Most of today's digital systems are build with sequential logic, including virtually all computer systems. A sequential circuit is a digital circuit whose outputs depend on the history of its inputs. Thus, sequential circuits have a memory that permits significantly more complex functional behaviors than combinational circuits are capable of.

A Sequential logic circuit is a form of the binary circuit its design employs one or more inputs and one or more outputs, whose states are related to some definite rules that depend on previous states. Both the inputs and outputs can reach either of the two states logic 0 low or logic 1 high. In these circuits, their output depends not only on the combination of the logic states at its

The block diagram of a sequential logic is shown below. Sequential logic circuits are used to construct finite state machines, which are basic building block in all digital circuitry, and also in memory circuits. Basically, all circuits in practical digital devices are a mixture of combinational and sequential logic circuits. Example
