“…Due to their simplicity and ease of use, UGCs are very promising in active circuit design. The available literature provides a wide number of recently published papers dealing with the use of such cells for the design of sinusoidal oscillators (Gupta & Senani, 2006;Senani, 1985;Soliman, 2010Soliman, , 2011, filters (Lin, Weng, Peng, Lee, & Kuo, 1998;Senani, Bhaskar, Singh, & Sharma, 2013;Soliman, 2009;Tlelo-Cuautle, Moro-Frías, & Fakhfakh, 2008;Tlelo-Cuautle, Sánchez-López, & Moro-Frías, 2010), negative impedance converters (Keskin & Hancioglu, 2004;Keskin & Toker, 2004), Chua circuits (Sánchez-López et al, 2008), etc. However, no systematic synthesis technique is provided.…”
