Abstract: A CMOS current-mode companding multiplier/divider composed of three compact logarithm circuits and one compact exponential circuit is proposed. Approaches for constructing the logarithm circuits and the exponential circuit are based on second-order Taylor series approximations. By gathering the three logarithm results and passing through the exponential circuit, we can obtain the result of zp(xq/yr). The circuitry complexity is very low with only 12 transistors. The simulation results indicate that the relative errors of the proposed circuit are small for small (p+q+r).
