Abstract

The intention of this letter is to draw the attention of journal as well as all the readers towards the duplication so that the reputation of the journal and ethics in the research could be maintained.

Keywords

Current mode circuit Multifunction current differencing cascaded transconductance amplifier (MCDCTA) Multiple sinusoidal oscillator (MSO) Analog integrated circuit 
This letter is concerned with the paper [1] recently published in this journal. The purpose of this note is to draw the attention of the journal that the same paper has already been published in [2]. The title of the paper, all headings of the manuscript, analysis part of the paper, proposed circuit, simulation results, tables and all references are the same. The paper [1] proposes a new element called multifunction current differencing cascaded transconductance amplifier (MCDCTA) as shown in Fig. 1 here for ready reference. Another circuit of multiphase sinusoidal oscillator has also been proposed in paper [1] by using MCDCTA as shown in Fig. 2 here for ready reference. These proposed circuits are the significant part of the paper. However, these two circuits have already published in [2] earlier with different author names. The paper [1] includes the hardware result and possible CMOS realization of the MCDTA which is not in [2].
