Supplementary single active device based grounded immittance function simulators

Abstract

New five grounded immittance function simulators are proposed in this paper. The first one is a positive lossless grounded inductor simulator which employs just one inverting buffer plus-type second-generation current conveyor while the other four proposed circuits include only one non-inverting current feedback operational amplifier. The second and third ones are negative lossless grounded inductor simulators. The fourth one is a positive inductor with a series positive resistor while the last one is a negative capacitance multiplier. All of the proposed circuits except the first one consist of only grounded capacitor(s). However, all of the proposed circuits need a single passive component matching condition. A band-pass filter composed of the first proposed circuit is given as an example. Also, frequency dependent non-ideal gain effects on the performance of all the circuits are given. The results of a lot of SPICE simulations are carried out by using 0.13 µm IBM technology parameters where ± 0.75 V DC symmetrical power supply voltages are utilized. In order to demonstrate the performance of the first proposed circuit, an experimental result is given as an example.
