Abstract :
A current-mode circuit consisting of dynamic current copiers is presented. The circuit can perform the sum of two input currents weighted by any two integer numbers. Based on this circuit, an accurate current amplifier with an amplification factor equal to the ratio of two arbitrary positive nonzero integers can be built.
