We modify the two operand ripple carry addition followed in conventional Carry SeLect Adder (CSLA) with a simple and efficient gate level circuit to reduce area and delay significantly. For this, we use an increment 1 block for generating the sum outputs with carry input 1 instead of second pair ripple carry adder as in conventional CSLA. The novelty of the proposed approach is that it reduces area, and the delay due to carry propagation in second pair of adder cells. The proposed CSLA adder has been designed using structural VHDL code and synthesized using Altera Quartus II. Experimental results show that the proposed design outperform the previous approaches in terms of delay and area reduction.

These simulated designs with appropriate parameters are implemented on the fabrication prototypes which have been validated with help of Agilent Microwave Analyzer (N99917A). These proposed MPAs and dielectric equivalent human breast model that have been validated using the di®erent dielectric strengths of coupling mediums are presented. These MPAs and dielectric equivalent human breast model have been validated using the existing Debye test bed. The coverage and vector dimension of tumor tissues have been detected using the Monostatic radar approach in the E F and É U shaped MPAs-based existing Debye test bed setups. This paper conclude that Fractional Bandwidth (FBW) of E F shaped MPA is 26.79% greater than É U shaped MPA of 21.67%. Hence, the E F and É U shaped MPAs prototypes are suitable for breast cancer diagnosis systems. The prototypes' depth, coverage and vector dimensions are presented in this paper.

The death rate has doubly risen in the past 30 years. The various diagnosis systems are authorized and followed to reduce the death rate. The Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) are existing diagnosis trials. The X-ray mammography (XRM) is an efficient diagnostic tool but it has some limitations in the screening detection methods. They are, the heavy chemical dose applied on the human breast of body to affect ionization effects within the body and harmful radiation effects during the clinical tests. Both of the above results provide the injurious health issues. Normally, these radiology diagnostic trials do not offer the tissue's sample based analyzed report. These drawbacks of MRI, XRM and other existing techniques are recovered using the Microwave Imaging (MI) methods. The available diagnostic methods (Magnetic resonance imaging, Microwave Radiometry) are studied and compared with microwave imaging method is presented in this survey.

Due to the rapidly growing mobile industry not only the speed arithmetic unit but also less area and low power arithmetic units are needed. The prerequisite of the adder is that it is predominantly fast and secondarily efficient in chip area. Several types of adders are available in practice; each type is used for meticulous purpose based on their performance and features. In this paper, the multiplexer based full adder is implemented in the design of various adders and they are compared on the basis of their execution parameters such as area, delay and power distribution by using conventional full adder and multiplexer based full adder.

This novel comparator architecture achieves both low power and high-speed operation, particularly at low-input data activity environments. The proposed comparator is designed using VHDL code and synthesized using ALTERA QUARTUS-II. Experimental evaluation of the proposed and state of-the-art designs revealed that the proposed comparator design exhibits a reduction in delay by 49.8% and gate count by 42.6% for a 16 bit design, compared to the best of the schemes used for comparison.

Optimizing the speed and area of the multiplier is a major design issue. A High Speed Serial-Serial Multiplier (HS-SSM) using half grid cycle for Ortho Frequency Division Multiplexing (OFDM) is proposed. In half grid cycling the data is fed at the input both during positive and negative edge of the clock. So more than one partial product is computed in each cycle. The computation of more than one partial product in each cycle reduces total delay of multiplication. The proposed HS-SSM and state-of the art multipliers are designed using VHDL coding and simulated using ALTERA QUARTUS II. The experimental results revealed that the proposed HS-SS multiplier performed better in terms of delay reduction. This accounts for the best Power Delay Product (PDP) and Area Delay Product (ADP) of the proposed multiplier. A HS-SS multiplier using half grid technique is proposed. Extensive comparison with the conventional and state-of-the art designs revealed the best performance of the proposed serial multiplier in terms of delay and PDP reduction. An implementation of the proposed multiplier design in OFDM block for signal processing revealed its suitability for high speed application.

drawback of high frequency data manipulation. Optimizing the speed and area of the multiplier is
a major design issue. A High Speed Serial-Serial Multiplier (HS-SSM) using half grid cycle for
Ortho Frequency Division Multiplexing (OFDM) is proposed. In half grid cycling the data is fed
at the input both during positive and negative edge of the clock. So more than one partial product
is computed in each cycle. The computation of more than one partial product in each cycle
reduces total delay of multiplication. The proposed HS-SSM and state-of the art multipliers are
designed using VHDL coding and simulated using ALTERA QUARTUS II. The experimental
results revealed that the proposed HS-SS multiplier performed better in terms of delay reduction.
This accounts for the best Power Delay Product (PDP) and Area Delay Product (ADP) of the
proposed multiplier. A HS-SS multiplier using half grid technique is proposed. Extensive
comparison with the conventional and state-of-the art designs revealed the best performance of
the proposed serial multiplier in terms of delay and PDP reduction. An implementation of the
proposed multiplier design in OFDM block for signal processing revealed its suitability for high
speed application.
