Abstract: A MOSFET controlling multiplier for obtaining the precise function of the operational multiplication by offsetting the offset voltage of MOSFET to remove the non-linear current of MOSFET, utilizing symmetrical voltage sources and a current mirror circuit is disclosed. The MOSFET controlling multiplier utilizes a MOSFET linear means for linearly varying the output current I to a node A in accordance with an input voltage from an input voltage source Vg and a symmetrical input voltage from voltage sources Vx and -Vx. The input voltage from the input voltage source Vg is operatively associated with the symmetrical input voltage from the voltage sources Vx and -Vx. An impedance element Z outputs a voltage Vo, with the impedance element Z being connected to the node A of the MOSFET linear means and the ground.
