A novel analogue CMOS circuit is presented which performs the arithmetical squaring of a voltage, using the square-law characteristic of the MOS transistor in saturation. The core circuit is constructed from four identical building blocks, which are... Read More about Two quadrant analogue squarer circuit based on MOS square-law characteristic.
