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
