What is Wave Dynamic Differential logic?
Wave Dynamic Differential Logic (WDDL) is provided, wherein a differential logic stage is pre-charged or pre-discharged by a previous logic stage, such as, for example, a previous SDDL stage, a WDDL stage, etc.
Which gate is nor or path?
The NOR gate is a combination OR gate followed by an inverter. Its output is “true” if both inputs are “false.” Otherwise, the output is “false.” The XNOR (exclusive-NOR) gate is a combination XOR gate followed by an inverter. Its output is “true” if the inputs are the same, and “false” if the inputs are different.
What is required by CMOS domino logic?
Domino logic is a CMOS-based evolution of the dynamic logic techniques based on either PMOS or NMOS transistors. It allows a rail-to-rail logic swing.
What are the basic gates in CMOS logic family?
About the Basic CMOS Logic Gates Two primary connections are the two-input NAND gate and the two-input NOR gate. A NAND gate places two n-channel transistors in series to ground and two p-channel transistors in parallel connected to +V. Only when both inputs are logic 1, the output goes to logic 0.
Does NAND equal or?
A NAND gate is equivalent to an inverted-input OR gate. An AND gate is equivalent to an inverted-input NOR gate. A NOR gate is equivalent to an inverted-input AND gate. An OR gate is equivalent to an inverted-input NAND gate.
What is TTL family?
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first “transistor”) and the amplifying function (the second “transistor”), as opposed to resistor–transistor logic (RTL) or diode–transistor logic (DTL).
What are the two phases of operation of dynamic CMOS logic?
The operation of this circuit is divided into two major phases: precharge and evaluation, with the mode of operation determined by the clock signal CLK.
What are the advantages of dynamic CMOS logic?
1) The number of transistors required here are less (N+2) as compared to 2N in the Static CMOS circuits. 2) This circuit is still a ratio less circuit as in case of Static. 3) The static power loss is very less in a dynamic logic circuit. 4) Faster switching speed because of lower load capacitance (CL) and Cint.
Which transistor is used in CMOS logic?
CMOS circuits use a combination of p-type and n-type metal–oxide–semiconductor field-effect transistor (MOSFETs) to implement logic gates and other digital circuits.
Is CMOS a transistor?
It means that CMOS uses the power efficiently. Hence, CMOS is used in most modern processors, such as microprocessors. It stands for Application Specific Integrated Circuits. CMOS is considered the standard transistor for the fabrication of chips.
Is an inverter a gate?
In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. In mathematical logic it is equivalent to the logical negation operator (¬). The truth table is shown on the right.
Why is NAND gate called universal gate?
Thus, the NAND gate is a universal gate since it can implement the AND, OR and NOT functions. NAND Gate is a Universal Gate: To prove that any Boolean function can be implemented using only NOR gates, we will show that the AND, OR, and NOT operations can be performed using only these gates.
