To develop low-power, high-speed and area-efficient design for portable electronics devices and signal processing applications is a very challenging task. Multiplier has an important role in digital signal processing. Reducing the power consumption of multiplier will bring significant power reduction and other associated advantages in the overall digital system. In this paper, a low-power and area-efficient two-dimensional bypassing multiplier is presented. In two-dimensional bypassing, row and column are bypassed and thus the switching power is saved. Simulation results are realized using UMC 90[Formula: see text]nm CMOS technology and 0.9[Formula: see text]V, with Cadence Spectre simulation tool. The proposed architecture is compared with the existing multiplier architectures, i.e., Braun’s multiplier, row bypassing multiplier, column bypassing multiplier and row and column bypassing multiplier. Performance parameters of the proposed multiplier are better than the existing multipliers in terms of area occupation, power dissipation and power-delay product. These results are obtained for randomly generated input test patterns having uniform distribution probability.

The design objective is to implement a Low power, High speed and High resolution Flash ADC with increased sampling rate. To make this possible the blocks of ADC are analyzed. The resistive ladder, comparator block, encoder block are the major modules of flash ADC. Firstly, the comparator block is designed so that it consumes low power. A NMOS latch based, PMOS LATCH based and a Strong ARM Latch based comparators were designed separately. A comparative analysis is made with the comparator designs. Comparators in the design is reduced to half by using time domain interpolation. Then a reference subtraction block is designed to generate the subtraction value of voltages easily and its given as input to comparator. Then a more efficient and low power consuming fat tree encoder is designed. Once all the blocks were ready, a 8 bit Flash Analog to Digital Converter was designed using 90nm CMOS technology and all the parameters such as sampling rate, power consumption, resolution were obtained and compared with other works.
