Connectivity in any terms between machine to machine, machine to people or vice versa and between people is getting more importance in todays` community life. This reality leads to an increasing interest for intensified and complex communication standards to be used or investigated. One of the most important candidate solutions for these kinds of communications are encrypted and cognitive communication techniques. Main characteristic advantages of the circuits used in encrypted and cognitive communication systems will be highlighted as, agility and configurability. In this study, it`s aimed to provide circuit solutions for encrypted and cognitive communication systems with lower power consumption and higher bandwidth with respect to the investigated ones in the literature. CCCII circuits in this study are designed with STMicroelectronics` 28nm Process to take advantageous properties of a top notch process and applications with frequency agile and configurable filters realized as a first example application in this process. Main goal of this study is to support different GPS protocols with unique filter circuit as an application.
