An integrable current-mode root-n circuit

In this paper, a simple circuit design technique for realizing an integrable current mode nth- order rooting circuit based on a class AB configuration and a translinear loop implemented from bipolar transistors is described. The proposed circuit can provide two-quadrant nth- order rooting output signal, wide dynamic range and the circuit are readily integrable. Some PSPICE simulation results are also included demonstrating the characteristic of the proposed technique.
