Abstract :
A novel technique, able to theoretically nullify the input resistance of a generic current-in circuit is presented. The method does not reduce the dynamic swing of the original circuit to which it is applied, hence allowing low-voltage operations to be achieved. A design example, based on a very simple class A CMOS CCII operating with a single 2-V power supply, is given. Simulations using 1.2-μm process parameters show a reduction of the resistance at terminal X of about 98%, while preserving the full dynamic swing
