   Abstract:
   The current conveyor-based circuits have many resemblances to ones built-up with operational amplifiers. In the latter, the feedback resistor has a lower bound to assure stability, while in the former, it is the load resistor which is limited by an upper bound. Simple models for CCII are unable to predict high frequency phase lag, mainly due to the inductive effect at terminal X, and to higher order poles in the voltage and current buffers. All these effects are important particularly in high performance CCII implementations. Their effect is more noticeable and negative when the circuit is not designed to optimize the own characteristics of the CCII.
