Abstract :
A novel current-mode analog multiplier/divider based on a voltage-translinear implementation of a geometric-mean circuit is presented, featuring favorable precision and wide dynamic range. It is suitable for standard CMOS fabrication and can be successfully applied in a wide range of analog systems. Two versions, based on stacked and up-down voltage-translinear loops, respectively, are described and verified by simulation
