This paper presents a method towards automatic structural synthesis of analog multiplier based on a hierarchical topology "super-topology", which is abstracted from the most standard four-quadrant multipliers. The essential components in the super-topology are four identical cells, which consist of several MOS-transistors and determine features and performances of multipliers. We build all possible cells within 3 transistors. Experimental results present three new multiplier structures with simulation results to show the creativity of our method.
