High-valued passive element simulation using low-voltage low-power current conveyors for fully integrated applications

In this brief, we describe how, using low-voltage low-power second-generation current conveyors, it is possible to simulate the frequency behavior of high capacitances and inductances by utilizing only elements suitable for an integrated implementation. The effect of current conveyor nonidealities has been taken into account. The simulated inductances and capacitances have been utilized, as an example, in the design of a fully integrated bandpass filter. PSPICE simulations, performed employing a standard CMOS technology (ALCATEL Mietec 0.5 μm) and showing good performance of the presented circuits, are also reported
