  • Abstract
    A new circuit configuration for an MOS four-quadrant analog multiplier circuit is presented. It is based on the square-law characteristics of the MOS transistor. Two versions have been realized. The first has a linearity better than 0.14 percent for an output current swing of 36 percent of the supply current and a bandwidth from dc to 1 MHz. The second version has floating inputs, a linearity of 0.4 percent at an output current swing of 40 percent of the supply current and a bandwidth from dc to above 4.5 MHz.
