Description

This paper describes the realization of an inductor using transistor mutators with differentiators which are suitable for operation in high frequency. The mutator is an active two-port linear network for transforming one type of nonlinear network element into another type. A proposed biquadratic filter realizes some kinds of second order transfer functions. The filter circuit is composed of differential mutators operating under the low power dissipation. Taking account of the imperfection of transistors，an analysis of the circuit at high frequency range and its discussion are performed. Next，the worst-cases sensitivity between integral mutators and differential mutators is estimated. It can be seen from the simulation results that good characteristics are obtained in high frequencies around several 10MHz. As a result，the availability of the proposed circuit is confirmed.
