| dc.description.abstract | Analogue IC(Integrated Circuit) design is historically seen as a voltage dominated form of signal processing. In fact, the analogue devices that are often used (e.g. transistors) are current output devices, so we can utilize them up to their limits in bandwidth which is one of the important issues in analogue circuits.Current mode design has recently started appearing in the literature. The advantages are very important in IC design. The most important issues are low power consumption and less space which are the key considerations in VLSI(Very Large Scale Integration). Because of working with quite low currents the power consumption is impressively low. Low current also means small W/L ratios so that less space is needed. Security is obtained by chaotic behavior of circuits that the communication is based on synchronizing two chaotic circuits. Such a system brings security to analog communication like a scramble type processing. The VLSI implementation can make this type of communication systems smaller. The advantages and design parameters of current mode circuits will be examined with the basic building blocks and it will be applied on a chaotic current mode communication system. This means that even portable devices for analog communication like pocket phones can be possible in the marketplace. | |
