摘要

本文介绍了基于CCII的高频振荡器和多功能滤波器。对这些结构特征和CCII非理想性效应进行了系统级研究。作者强调了这样一个事实，即所提出的应用非常适合集成，因为它们的特性可以通过对其偏置电流的简单动作来调谐。基于改进的高频跨线性CCII实现了这些拓扑结构。该振荡器具有可变振荡频率，可在[333 MHz-867MHz]范围内通过改变直流电流在50muA和400muA之间进行调谐。此外，还实现了两种基于电流型和电压型的多功能滤波器。电流模式滤波器在512MHz-1GHz范围内具有可调谐的固有频率，电压模式滤波器也实现具有等于100MHz的固有频率

High frequency CCII based oscillators and multifunction filters

In this paper, high frequency CCII based oscillators and multifunction filters are presented. A system level investigation of these configurations characteristics and CCII nonidealities effects are done. The authors emphasize the fact that the proposed applications are well suited for integration since their characteristics can be tuned by simple action on their bias current. Implementations of these topologies based on an improved high frequency translinear CCII were done. The oscillator has a variable oscillation frequency tunable in the range [333 MHz-867MHz] by varying a dc current between 50muA and 400muA. Moreover, two based current mode and voltage mode multifunction filters were implemented. The current mode filter has a tunable natural frequency in the range [512MHz-1GHz] and the voltage mode filter is also implemented having a natural frequency equal to 100MHz
