Abstract :
Simple current-mode non-linear computational circuits based on a basic cell built with floating-gate MOS transistors are proposed. The basic cell is used to construct a current square-root circuit, a current squarer and a four-quadrant current multiplier. The circuits offer large input range, low harmonic distortion and high linearity. Spice simulation results verify the performance of the proposed circuits
