摘要：
An improved current conveyor circuit topology based around the use of a current-steering output stage, rather than the more usual current mirrors, is described in this paper. The primary benefit of this approach is a significantly enhanced current transfer linearity through reduced reliance on output-device matching requirements. Outline performance details are given for a discrete version of the circuit and a prototype IC fabricated using this technique.
