  • Abstract
    For the original article see ibid., vol.SC-21, no.3, p.430-5 (1986). A CMOS four-quadrant multiplier based on 12 transistors was proposed by K. Bult and H. Wallinga in the above-titled paper using four floating-well transistors to keep VT constant. It is shown analytically by the commenter that the floating wells can be avoided with little penalty on distortion, but with reduction in signal output. A four-transistor multiplier is also analyzed
