PCB DESIGN USING ORCAD



Or CAD is a suite of tools from Cadence for the design and layout of printed circuit boards. Or CAD really consists of two tools. Capture is used for design entry in Schematic Form. Layout is a tool for designing the physical Layout of Components and Circuits on a PCB. During the design process, you will move back and forth between the two tools. Or CAD Capture design entry is the most widely used Schematic entry system in electronic design today for one simple reason. Fast and universal design entry. Whether you are designing a new analog circuit, revising Schematic diagram for an existing PCB or designing a digital block diagram with an HDL Module, ORCAD Capture provides simple Schematic commands you need to enter, modify and verify the design for PCB

Or CAD Layout offers PCB designers and PCB design terms the power and flexibility to create and share PCB data and constraints across the design flow. Or CAD delivers the entire capacities designer from net list to place and route, to final output. The erase of use and intuitive capabilities of Or CAD Layout provides for quick standup and rapid learning. PCB consists of a number of Electrical and Non Electrical layers. Two the four electrical layers are fairly common for simple circuit boards. 8 to 20 layers can often in many industrial applications. The top and bottom layers are used for outing nets between parts while the inner two layers are solid copper for the connections to the power and ground. A fiberglass or epoxy resin dielectric material separates each of the layers

Evolution of Cellular System

Multiple Input Multiple Output (MIMO)

Over the past few years, it has been shown that using multiple antennas can significantly increase the capacity and robustness of communication systems in fading environments. Capacity grows with the number of antennas used. Approximately twice the amount of information can be communicated using two transmit antennas and two receive antennas, without spending any extra time, bandwidth, nor power.

The multiple input multiple output (MIMO) scheme deploys multiple antennas at the transmitter or/and at the receiver. The data stream from a single user is demultiplexed and fed into the respective transmitting antennas all of which radiate in the same frequency band. By sharing the same frequency band the spectral efficiency is improved. The receiver is assumed to have ideal channel estimates so it can separate and decode the symbols transmitted from each antenna. The ability to separate out the symbols is due to the fact that in a scattering environment, the signals received at each receiving antenna from each transmitting antenna appear to be uncorrelated.

Wireless!!!!!!!


Wireless communications is, by any measure, the fastest growing segment of the communications industry. Cellular systems have experienced exponential growth over the last decade and there are currently around two billion users worldwide. Indeed, cellular phones have become a critical business tool and part of everyday life in most developed countries, and are rapidly supplanting antiquated wireline systems in many developing countries. In addition, wireless local area networks currently supplement or replace wired networks in many homes, businesses, and campuses. Many new applications, including wireless sensor networks, automated highways and factories, smart homes and appliances, and remote telemedicine, are emerging from research ideas to concrete systems. The explosive growth of wireless systems coupled with the proliferation of laptop and palmtop computers indicate a bright future for wireless networks, both as stand-alone systems and as part of the larger networking infrastructure. However, many technical challenges remain in designing robust wireless networks that deliver the performance necessary to support emerging applications.
