“…In addition to the given study above our investigation also shows that the proposed circuits in Refs. 2-46 suffer from some additional weaknesses: use of BJTs in its internal structure 2,[13][14][15][16][17]19,29,30,[36][37][38]40,[43][44][45] , which is not preferred due to effect of thermal voltage, use of multiple current output terminal ABB (device with three or more outputs) 4,12,19,21,22,37,38,40,43 , which increases the number of transistors in structure, employs excessive number of passive components (three or more) [5][6][7][8][24][25][26][27][28][29]31,34,35,45 , two or more capacitors are required 5,26 , capacitor is connected in series to low input-impedance terminal of ABB 7,12,15,17,26,[32...…”
