This paper presents a fast, low-power, binary carrylookahead, 64-bit dynamic parallel adder architecture for highfrequency microprocessors. The adder core is composed of evaluate circuits and feedback reset chains implemented by selfresetting CMOS (SRCMOS) circuits with enhanced testability. A new tool, SRCMOS pulse analyzer (SPA), is developed for checking dynamic circuits for proper operation...

Different adder circuits are elementary blocks in many contemporary integrated circuits, which are not only employed to perform addition operations, but also other arithmetic operations such as subtraction, multiplication and division. Full adder is the basic building block of any adder circuit. Area, speed and power are the three main design metrics for any VLSI circuit. In this work, eight di...

This paper analyzes the difference between two techniques of power saving circuit design. As the number of transistors increases power consumption and the need for more power efficient products increases there is greater motivation to design circuits to fulfill these expectations. We will give a comparison between these two technologies using an adder as the basic circuit. We will compare the p...

We compare two 16 bit adders based on the Manchester Carry Chain (MCC) circuit topology using the TSMC .25 µm process technology. The first circuit is a synchronous 16 bit adder based on an optimized 4-bit MCC where the carry out of each of the 4-bit MCCs are ripple carried into the next MCC block through an edge sensitive D-Flip Flop. The second circuit is an asynchronous adder, which uses the...

Addition is one of the most crucial operation in microprocessors which must be performed within a predefined deadline (critical path). Variation is a phenomenon which negatively affects the performance of this operation. This paper proposes a new Low-Power Variation-Mitigant (LPVM) adder design using intrinsic behavior of addition operation. The LPVM approach drastically decrease the probabilit...

ABSTRACT : A circuit design for a low-power full adder array-based multiplier in domino logic is proposed. It is based on Wallace tree technique. Clocked architecture results in lower power dissipation and improvements in power-delay product. The proposed technique is general and can be used in all domino logic circuit designs. Higher order multipliers like 16x16, 32x32 may also be implemented ...

Adder being the basic hardware block of any arithmetic operation, the major constraint in the field of signal processors, data processors to perform any operations are highly dependent on the adder performance of the circuit. The gate level implementation of the carry select adder (CSLA) and modified carry select adder has significantly reduced the area and power consumption which replaced the ...

This paper presents hardware-efficient Delta Sigma linear processing circuits for the next generation low-power VLSI devices in the Internet-of-things (IoT). We first propose the P-N (positive-negative) pair method to manipulate both the analog value and length of a first-order Delta Sigma bit sequence. We then present a binary counter method. Based on these methods, we develop Delta Sigma doma...
