What is DCVS in VLSI?
Differential cascode voltage switch (DCVS) logic is a CMOS circuit technique that has potential advantages over conventional NAND/NOR logic in terms of circuit delay, layout density, power dissipation, and logic flexibility.
What is DCVS logic?
Differential Cascode Voltage Switch (DCVS) is a well-known logic style, which constructs robust and reliable circuits. Two main strategies are studied in this paper to form static DCVS-based standard ternary fundamental logic components in digital electronics.
What is switch logic in VLSI?
Explanation: Switch logic is based on pass transistors or transmission gates. Pass transistor describes several logic families used in the design of integrated circuits. This logic reduces the count of transistors used to make different logic gates, by eliminating redundant transistors.
What is RTL DTL TTL and CMOS?
The families (RTL, DTL, and ECL) were derived from the logic circuits used in early computers, originally implemented using discrete components. One example is the Philips NORBIT family of logic building blocks. Present-day “building block” logic gate ICs are based on the ECL, TTL, CMOS, and BiCMOS families.
What kind of logic is used in CVSL?
Cascode Voltage Switch Logic (CVSL) was developed in IBM [1] as an improvement over the use of pseudo n-MOS. It comes in two forms: single-output and differential output (or double-rail). The later form of the logic is also known as DCVSL (Differential Cascode Voltage Switch Logic). Wiley STM / Editor: VLSI Digital Circuits Design,
Which is advantage of dcvsl over NAND / NOR?
Abstract The Differential Cascode Voltage Switch Logic (DCVSL) is a CMOS circuit technique which has potential advantages over conventional NAND/NOR logic in terms of power dissipation, circuit delay, layout density and logic flexibility.
Which is the basic building block of DCVS logic?
A DCVS Logic is based on 2:1 Multiplexer which is used as an important element in many various circuit designs such as implementation of memory circuits and FPGA. It is valuable in situations where price is a factor and for modularity. A 2:1 Multiplexer is considered to be the basic building block of the “switch logic”.
Who are the main competitors of VLSI Technology?
When VLSI and its main ASIC competitor, LSI Logic, were establishing the ASIC industry, commercially available tools could not deliver the productivity necessary to support the physical design of hundreds of ASIC designs each year without the deployment of a substantial number of layout engineers.
