A current-mode analog computational circuit can be controlled to produce multiplying, squaring, divider and inverse functions and corresponding current outputs. The current-mode analog computational circuit is based on an implementation using MOSFETs operating in a sub-threshold region as can provide relatively ultra-low power dissipation. Furthermore, the current-mode analog computational circuit can be operated from a &#xb1;0.75 V DC supply. Tanner simulation results conducted using a 0.35-&#x3bc;m TSMC CMOS process confirmed the functionality of the multiplying, squaring, divider and inverse functions of the circuit. The current-mode analog computational circuit advantageously can have a total power consumption of 2.3 &#x3bc;W, a total harmonic distortion is 1.1%, a maximum linearity error of 0.3% and a bandwidth of 2.3 MHz.
