A latch-adder based array multiplier, targeting for low V<SUB>DD</SUB> and low power operations, is presented. It employs a dynamic version C²MOS full adder design incorporating the latch function with the adder cell efficiently. The adder outputs are further equipped with keeper logic. Latch control signals are generated by a chain of delay cells and applied to each row of the adder array. The computations in the adder array are thus aligned row-wise and proceed orderly to reduce spurious signal switching activities. The delay disparity in sum and carry paths within an adder cell is taken into account and time skewed latch control signals are applied separately. Simulation results on 8×8 and 16×16 multiplier designs show the proposed ones have the lowest power consumptions in 5 designs under comparison. The power saving against conventional array multiplier designs is up to 36%. The proposed 8×8 multiplier design is further implemented using the TSMC 0.18 um CMOS technology. When operating in the nominal condition, i.e. (0.6 V, 1 MHz), the design has a measured power consumption of 1.28 uW. For the target 1 MHz working frequency, the required V<SUB>DD</SUB> can be even reduced to 0.5 V and the power consumption is only 0.91 uW.
