"abstract": "Versatile dual-mode class-AB CMOS four-quadrant\r\nanalog multiplier circuit is presented. The dual translinear loops and\r\ncurrent mirrors are the basic building blocks in realization scheme.\r\nThis technique provides; wide dynamic range, wide-bandwidth response\r\nand low power consumption. The major advantages of this\r\napproach are; its has single ended inputs; since its input is dual translinear\r\nloop operate in class-AB mode which make this multiplier\r\nconfiguration interesting for low-power applications; current multiplying,\r\nvoltage multiplying, or current and voltage multiplying can\r\nbe obtainable with balanced input. The simulation results of versatile\r\nanalog multiplier demonstrate a linearity error of 1.2 %, a -3dB bandwidth\r\nof about 19MHz, a maximum power consumption of 0.46mW,\r\nand temperature compensated. Operation of versatile analog multiplier\r\nwas also confirmed through an experiment using CMOS transistor\r\narray.",
