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.

This paper proposes a method for an inductance simulation by using GaAs MESFET (Gallium Arsenide MEtal Semiconductor Field-Effect Transistor) devices. The realization method is based on the use of a GaAs voltage-to-current transducer and is also suitable for implementing in monolithic integrated circuit form. The circuit has wide bandwidth, good linearity and the simulated inductive reactance value is a linear function of resistor and capacitor. The PSPICE simulation results show that the properties of the circuit are in close agreement with the theoretical prediction.
