Quaternary Adder

In VLSI, design and implementation of circuits with MOS devices and binary logic are quite usual. The Main Objective is to design a low power and minimum leakage Quaternary adder. The VLSI field consists of Multi-valued logic (MVL) such as ternary and Quaternary Logic (QTL). The Failures such as Short Channel Effects (SCE) Impact-ionization and surface scattering are in normalized aspects. The Quaternary radix on MVL (multi-valued logic) monitors and reduces the area. The Quaternary (four-valued) logic converts the quaternary signals and binary signals produced by the by the existing binary circuits. The Proposed is carried out with LTSPICE tool and CMOS technology.

Field emission SEMs (FE-SEMs) are becoming popular due to their high resolution needs. In the field of semiconductor product, it is demanded to use the low accelerating voltage FE-SEM to avoid the electron irradiation damage and the electron charging up on samples. However the accelerating voltage of usual SEM with FE-gun is limited until 1 kV, which is not enough small for the present demands, because the virtual source goes far from the tip in lower accelerating voltages. This virtual source position depends on the shape of the electrostatic lens. So, we investigated several types of electrostatic lenses to be applicable to the lower accelerating voltage. In the result, it is found a field emission gun with a conical anode is effectively applied for a wide range of low accelerating voltages.A field emission gun usually consists of a field emission tip (cold cathode) and the Butler type electrostatic lens.

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.
