组合逻辑没有反馈，电路的输出只与现时的输入有关。而时序逻辑电路有反馈，其输出不但与现实的输入有关，还与原来的输出状态有关，也就是有记忆功能了。
Design of Combinational and Sequential Circuits Using Novel Feedthrough LogicDynamic CMOS Logic circuitsLow powerRipple Carry Adder (RCA)In this paper a circuit design technique to reduce dynamic power consumption of a new CMOS domino logic family called feedthrogh logic (FTL)is presented. The ...
In this tutorial, we will learn about sequential circuits, their types, and the differences between combinational circuits and sequential circuits.BySaurabh GuptaLast updated : May 11, 2023 What are Sequential Circuits? The word sequential circuit means"a circuit whose output depends on the order or...
我们希望能够建造一个sequential circuit来存储state,满足以下条件: Memory 存储current state,可以通过output来获得这些bits; Combinational logic 通过current state和input来产生next state和output; Memory有2个input,其中一个是next state,另一个是LOAD控制信号,LOAD来决定什么时候用next state代替current state。 同时包...

Here, it can be seen that a sequential circuit is basically a combination of a combinational circuit and a memory element. The combinational circuit performs the logical operations specified, while the memory element records the history of operation of the circuit. This history is then used to ...

When CLK is low, two series terminals in N tree N are open and two parallel transistors in tree P are ON, thus retaining state in the memory cell. When clock is high, the circuit becomes simply a NOR based CMOS latch which will respond to input S and R. ...

and it is easy to compute its impact on the switching of the clock net by using combinational switching activity propagation techniques. However, sequential clock gating alters the sequential nature of the design. For example, to perform observability-based clock gating for the circuit shown in Fig...
