Abstract:


Objective: The interest concern towards the development of enabling technology towards new current mode devices has forced the designers and researchers for the invention of devices, which has having the characteristics like such as low power, robustness, compactness, efficiency and scalability.

Method: Second Generation Current Controlled Conveyor (CCCII) is the prevailing current mode device of the times today. Since its invention by A. Fabre, it has prominent applications in the field of analog signal processing and in biomedical applications too. In this manuscript, CCCII is used as an enabling device to design a Frequency Shift Keying (FSK) Generator.

Result: The proposed topology is designed using a single active device CCCII with least passive components. The circuit enjoys the features of like electronic tunability of frequency using the bias current.

Conclusion: It can be concluded that the FSK generator circuit designed using single CCCII confers better results in contrast to the existing structures. The maximum power consumption is 0.196 mW. The proposed circuit has the benefit of simple configuration, which is very much proficient for IC fabrication.
