    This paper introduces a voltage multiplier (VM) circuit
    which can step up a minimum voltage of 150 mV (peak).
    The operation and characteristics of this converter circuit
    are described. The voltage multiplier circuit is also tested
    with micro and macro scale electromagnetic vibrational
    generators and the effect of the VM on the optimum load
    conditions of the electromagnetic generator is presented.
    The measured results show that 85% efficiency can be
    achieved from this VM circuit at a power level of 18 μW
