Low voltage differential signaling, or LVDS, is an electrical signaling system that can run at very high speeds over cheap, twisted-pair copper cables. It was introduced in 1994, and has since become very popular in computers, where it forms part of very high-speed networks and computer buses.
LVDS uses the difference in voltage between two wires to signal information. The transmitter injects a small current, nominally 3.5 milliamperes, into one wire or the other, depending on the logic level to be sent. The current passes through a resistor o ....etc

LOW-POWER LOW -AREA MULTIPLIER BASED ON SHIFT AND ADD ARCHITECHTURE
Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement

Low-Voltage Differential Signaling (LVDS) is a new technology addressing the needs of today's high performance data transmission applications. The LVDS standard is becoming the most popular differential data transmission standard in the industry. This is driven by two simple features: Gigabits @ milliwatts! LVDS delivers high data rates while consuming significantly less power than competing technologies. In addition, it brings many other benefits, which include:

a)Low-voltage power supply compatibility
b)Low noise generation
c)High no ....etc

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.
