Adder Is Basic Unit For Any Digital System, Dsp And Microprocessor. The Main Issue In Design High Speed Full Adder Cell With The Low Power Dissipation. As We Know Cmos Technology Used For Vlsi Designing Cmos Has Many Drawbacks As High Power Short Channel Effect Etc. Then Cntfet (Carbon Nanotube Field Effect Transistor) Has Been Developed Which Has Same Structure As Cmos. The Difference Between Structure Of Cmos And Cntfet Is Their Channel. In Cntfet Channel Is Replaced By Carbon Nanotube. In This Paper We Compare Full Adder Circuit Using Cntfet With Gdi Technique And Cmos Implementation Of Adder Which Gdi Technique. Gdi Technique Is Used For Speed And Power Optimization In Digital Circuit. This Can Also Reduce The Count Of Transistor Which Affects The Size Of Device.

Abstract An analogue median filter, realised in a 0.35 μm CMOS technology, is presented in this paper. The key advantages of the filter are: high speed of image processing (50 frames per second), low-power operation (below 1.25 mW under 3.3 V supply) and relatively high accuracy of signal processing. The presented filter is a part of an integrated circuit for image processing (a vision chip), containing: a photo-sensor matrix, a set of analogue pre-processors, and interface circuits. The analysis of the main parameters of the considered median filter is presented. The discussion of important limitations in the operation of the filter due to the restrictions imposed by CMOS technology is also presented.

Structured Illumination Microscopy (SIM) is a widely used imaging technique that doubles the effective resolution of widefield microscopes. Most current implementations rely on diffractive elements, either gratings or programmable devices, to generate structured light patterns in the sample. These can be limited by spectral efficiency, speed, or both. Here we introduce the concept of fiber SIM which allows for camera frame rate limited pattern generation and manipulation over a broad wavelength range. Illumination patterns are generated by coupling laser beams into radially opposite pairs of fibers in a hexagonal single mode fiber array where the exit beams are relayed to the microscope objective’s back focal plane. The phase stepping and rotation of the illumination patterns are controlled by fast electro-optic devices. We achieved a rate of 111 SIM frames per second and imaged with excitation patterns generated by both 488 nm and 532 nm lasers.
