Multipliers are the most commonly used elements in today's digital devices. In order to achieve high data throughput in digital signal processing systems, hardware multiplication is the important factor. Depending on the applications which are emerging with the electronics devices, various types of multipliers are emerged. Among all the multipliers, the basic multiplier is Array Multiplier. This paper...
With the advent of the mobile devices, the main goal of today's SOC is not only to increase the performance but to maximize the performance per watt (perf/watt) furthermore to increase the battery life. But the main hurdle for achieving this is the leakage power. As the technology is scaling to few nanometers the leakage power has become predominant in the design. Power gating is one of the power...
Booth multiplier is a multiplication of two binary numbers in two's complement notation and the proposed project new technique introduced i.e. fixed width multiplier is part of booth multiplier, in this 5-2 compressor is used with pipelining so that it leads to decrease the absolute error and improve the accuracy and delay also less. Unlike previous conditional-probability methods, the proposed Multi...
Most of the applications of digital filters are found in communication and signal processing systems. The reliability of these systems is critical when more number of filters are used for a specific application. There are several advancements in VLSI technology i.e., number of circuits (filters) increased on a small chip. In this case we have to implement the fault tolerance in order to preserve the...
one of the important biological signals which is used to measure the health condition of the human being is an Electro Cardio Gram (ECG) Signal. This signal results because of the activity of the heart and consists of P, Q, R, S, T and U waves. QRS Detection is an important problem of research in Biomedical Engineering and Pan Tomkins Algorithm is one of the well-known techniques used for this purpose...
The Content addressable memory which is known as CAM operates faster as it obtains the output in one clock cycle. In this paper an effort is made to improve the search speed and reduce power consumption of content addressable memory, by combining charge sharing and segmentation techniques. To obtain high search speed a CAM compares its stored word simultaneously and identifies the location of the...
Modern circuit design is starving for compact and low power dissipating devices with long life. So investigations are made to minimize all kinds of non-linearities even like heat dissipation by an individual circuit or a system like modern DSP. Irreversible logic circuit dissipates more heat for every bit of information that is lost. Reversible logic circuit naturally takes care of heating because...
Nowadays, designers are working towards for the designs with low power, high speed, low offset voltage and reduced area. For complex designs comparator is one of the basic building blocks in low power applications. Hence designing of a comparator with above mentioned parameters is more challenging one. In this paper, we designed and simulated the different dynamic comparators which are already in...
Over the past decade VLSI manufacturing industry flourishing very rapidly. Now a days hundreds and thousands of millions of transistors that are incorporated on a chip. As the circuit complexity increasing design for test circuitry also became more complex. These complex test circuitry heavily stressed to check the functionality of the CUT (Circuit under Test). Compared with normal functional mode,...
The universal serial bus(USB) transceiver macro cell interface (UTMI) is a two wire, bi-directional serial bus interface. The USB2.0 specifications define three types of UTMI implementations depends on data transmission rates, those are low speed (1.5 MHz) only (LS), full speed (12 MHz) only (FS) and high speed (480 MHz)/full speed (12 MHz) (HS). UTMI consists of transmitting and receiving sections,...
