This paper presents a 0.5-V ultra-low voltage multiplier. In order to achieve ultra-low voltage and high speed operation, we modify the traditional pipelined architecture and adopt a PMOS forward body bias control technique, a symmetric signal path full-adder structure and a synchronous output D flip flop. Fabricated in 130nm CMOS technology, the measured operation rate of 8bit x 8bit pipelined multiplier get up to 320-MHz clock rate and the power consumption is about 1.48mW from 0.5-V power supply.
