This paper proposes a novel Fin FET-based HSFA for the multiplier in order to overcome the issues of low speed operation. It is advantageous to use Fin FETs to construct the arithmetic circuit while assessing the available works. The carry propagation and slow operation of the old technique are disadvantages. The CMOS-based compressor circuit, on the other hand, suffers from leakage current, which reduces its driving capabilities. High current DSP applications are well matched to the design's specifications. Even with a supply voltage of 1 volt, the proposed device has a decent driving capability. As a result, the circuit runs more quickly and has less latency. A transmission gate is used in the design of the suggested adder structure to selectively block or transfer data from the input to output. Half adder and adder are shown in the following illustrations. The smaller the transistor count, the less power it uses. The suggested Fin FET design for the smaller transistors has a superior driving capability than the CMOS equivalent. Additionally, when cascading, the Fin FET based adder may contribute to superior switch performance, such as when using ripple carry adder. There is also the possibility of a low operation, which may operate at Low wattage Electronic designs for high-performance and small devices have become increasingly dependent on the use of VLSI circuits. The power of a processor is determined in large part by the multiplier used in its design. Multiplier factor booth coding is being used to reorder the input bits in order to reduce facility use. The booth decoder works by rearranging the specified booth equivalent. The Booth decoder has the ability to expand the range of zeros. As a result, the power consumption of the design will be decreased even more. As soon as the input bit constant drops below zero, related rows or columns of an adder must be disabled, if possible
