Aj. Lopez-martin et A. Carlosena, Current-mode multiplier/divider circuits based on the MOS translinear principle, ANALOG IN C, 28(3), 2001, pp. 265-278
In this paper, novel current-mode analog multiplier/divider circuits based
on a pair of voltage-translinear loops are presented, featuring simplicity,
precision and wide dynamic range. They are suitable for standard CMOS fabr
ication and can be successfully employed in a wide range of analog signal p
rocessing applications. Two versions, based on stacked and up-down voltage-
translinear loops, respectively, are described. Experimental results are pr
ovided in order to verify their correct operation.
