A novel low-voltage low-power fully differential voltage and current gained CCII for floating impedance simulations

In this paper we present a new current-mode basic building block that we named voltage and current gained second generation current conveyor (VCG-CCII). The proposed active block allows to control and tune both the CCII Current gain and the voltage gain through external control voltages. It has been designed, at transistor level in a standard CMOS technology(AMS 0.35 mu m). with a low single supply voltage (2V), as a fully differential active block. The proposed integrated solution, having both low-voltage (LV) and low-power (LP) characteristics, can be applied with success in suitable IC applications Such as floating capacitance multipliers and floating inductance simulators, utilizing a minimum number of active components (one and two, respectively). Simulation results, related to floating impedance simulators, are in good agreement with the theoretical expectations. (c) 2008 Elsevier Ltd. All rights reserved.
