This paper presents a new realization of a grounded simulated inductor using a single dual output second-generation voltage conveyor (VCII +/-) as an active building block, two resistors and one grounded capacitor. The main characteristic of the proposed circuit is that the value of the series resistor can be significantly reduced. Thus, it has the property of improved low-frequency performance. Another feature is the use of a grounded capacitor that makes the proposed circuit attractive for integrated circuit (IC) realization. A simple CMOS implementation of the required VCII +/- is used. However, a single passive component-matching condition is required for the proposed structure. As an application example, a standard fifth-order high-pass ladder filter is also given. SPICE simulations using 0.18 mu m CMOS technology parameters and a supply voltage of +/- 0.9 V as well as experimental verifications, are carried out to support the theory.

Abstract

This paper presents a new realization of a grounded simulated inductor using a single dual output second-generation voltage conveyor (VCII +/-) as an active building block, two resistors and one grounded capacitor. The main characteristic of the proposed circuit is that the value of the series resistor can be significantly reduced. Thus, it has the property of improved low-frequency performance. Another feature is the use of a grounded capacitor that makes the proposed circuit attractive for integrated circuit (IC) realization. A simple CMOS implementation of the required VCII +/- is used. However, a single passive component-matching condition is required for the proposed structure. As an application example, a standard fifth-order high-pass ladder filter is also given. SPICE simulations using 0.18 mu m CMOS technology parameters and a supply voltage of +/- 0.9 V as well as experimental verifications, are carried out to support the theory.
