A realization of R-L and C-D parallel circuits using a CF/CCII

摘要

This paper proposes four types of CF/CCII (CCII with current follower) and novel four configurations for realizing admittance functions using CF/CCII as active elements. The circuits are composed of a CF/CCII and three passive elements, and can realize R-L and CD parallel impedance, and can also realize current-mode low-pass, band-pass, high-pass transfer functions by adding a capacitor or a resistor. The circuits have low passive sensitivities. PSpice simulation results of current-mode transfer functions are also given.
