CMOS CCCII: Structures, characteristics, and considerations

In this paper, a novel CMOS circuit of second-generation current controlled conveyor (CCCII) is proposed, which offers wide input voltage range and large 3 dB bandwidth of voltage-current transfer gain with high linearity under low supply voltage. The core of this CCCII adopts cross-coupled differential transistor pair as input stage instead of conventionally source-coupled and the principle of the circuit is analyzed theoretically in detail. This CCCII is implemented by PSPICE program in TSMC 0.18 lm RF CMOS technology and verified by simulation results. A current-mode universal filter which consists of two proposed CMOS CCCIIs is also simulated to validate the feasibility of the new circuit topology.

ÖZETÇEBu çalışmada akım kontrollu ikinci nesil akım taşıyıcılarla gerçeklenmiş ikinci ve dördüncü derece frekans atik süzgeç uygulamaları gösterilmiştir. Şifreli haberleşme, bilişsel radyo ve yazılım tanımlı radyo yapıları frekans atik süzgeç yapısı kullanır. Bu sistemler arka planda frekansı ayarlanabilir alıcılara, osilatörlere,vs ihtiyaç duyarlar. Tasarlanan frekans atik süzgeç yapısı tekil ayrık süzgeç yapısı işlenebilecek global yer belirleme sistemlerine (GPS, GLONASS, Beidou, GNSS ve Galileo) de uygulanabilir. Benzetimler için AMS 0.18µm teknoloji parametreleri kullanılarak Cadence ortamın da ayarlanabilir süzgeç performansı teyit edilmiştir. ABSTRACTIn this paper, second and fourth order frequency agile filter applications realized with second generation current controlled current conveyor is presented. Encrypted communication, cognitive radio and software defined radio structures use the frequency agile filter structure. These systems background need the reconfigurable frequency receveirs, oscillators or etc. The designed frequency agile filter structure is also applicable to the global positioning systems (GPS, GLONASS, Beidou, GNSS and Galileo) to be processed on a single discrete filter. The performance of the reconfigurable filter is verified in Cadence environment. AMS 0.18µm process paremeters are used for the simulations.
