Dynamic logic gates
In integrated circuit design, dynamic logic (or sometimes clocked logic) is a design methodology in combinational logic circuits, particularly those implemented in metal–oxide–semiconductor (MOS) technology. It is distinguished from the so-called static logic by exploiting temporary storage of information in … See more The largest difference between static and dynamic logic is that in dynamic logic, a clock signal is used to evaluate combinational logic. In most types of logic design, termed static logic, there is always some mechanism … See more As an example, consider the static logic implementation of a CMOS NAND gate: This circuit implements the logic function $${\displaystyle Out={\overline {AB}}}$$ If A and B are both high, the output will be pulled low. If either A or B are low, the output will be pulled … See more • Introduction to CMOS VLSI Design – Lecture 9: Circuit Families – David Harris' lecture notes on the subject.

This class of circuit is known as dynamic circuits. The clock signal is used to divide the gate operation into two halves. In the first half, the output node is pre-charged to a high or low logic state. In the

The logic gates are the basic building blocks of all digital circuits and computers. These logic gates are implemented using transistors called MOSFETs. A MOSFET transistor is a voltage-controlled switch. The MOSFET acts as a switch and turns on or off depending on whether the voltage on it is either high or low.
WebStatic Logic Gates In this chapter we discuss the DC characteristics, dynamic behavior, and layout of CMOS static logic gates. Static logic means that the output of the gate is always a logical function of the inputs and always available on the outputs of the gate regardless of time. We begin with the NAND and NOR gates. WebDynamic logic is an alternative to standard Static Logic that we discussed up till now. It generally consists of a PDN that is constructed identically to a CMOS PDN, but instead of a PUN, it has a pair of complementary transistors that connected to the clock. These divide the operation of the dynamic gate into Precharge and Evaluation phases.

WebSep 30, 2024 · Domino logic, a modification of the dynamic logic, can be used to cascade several stages. The configuration of a domino-logic multiple-inverter gate is shown in Fig. 3.36. It can be seen from Fig. 3.36 that the circuit is the same as that of the dynamic logic gate with the addition of a CMOS inverter at the output.
