Abstract :
A new circuit configuration for an MOS four-quadrant analog multiplier circuit is presented. It is based on the square-law I-V characteristics of the MOS transistor. Linearity is better then 0.14 % for an output swing of 36 % of the supply current. The bandwidth is from de to above 1 MHz.
