For the synchronous circuit, the input data is normally latched into sequential elements before it is processed by the following circuits.
This type is varied from synchronous circuit in which variations to the signal values in the circuit are activated by repetitive pulses called a clock signal.
Most of the adders have been designed using synchronous circuits although there is a strong interest in clock less/ asynchronous processors/circuits.
In case of sequential circuit, not affected by anonymous delays in the feedback path instead the memory element controls the output in accordance with the input at predetermined discrete intervals of time .Asynchronous circuit is faster than the synchronous circuit but the system becomes unstable resulting in difficulties.
In contrast to the synchronous circuits, asynchronous circuits perform handshaking between their components to perform all necessary synchronization, communication, and sequencing of operations.
