Реферат: A piezo MEMS mirror system that includes a drive system that drives a piezo MEMS mirror that generates an image on a portable device display. The drive system includes a DC-AC converter that operates to convert the DC power provided by the battery to AC power. The DC-AC converter may generate the AC power having a peak voltage that is at an intermediate level - being between the DC voltage of the battery, and the peak AC voltage generated by the drive system. The drive system also includes an output filter that uses a series-coupled inductance system (perhaps inductively coupled inductors in a differential mode circuit) in conjunction with a capacitance of the piezo MEMS mirror (and perhaps tuning capacitors to account for mirror fabrication deviations) to amplify the AC voltage of the AC power at a mechanical resonant frequency of the piezo MEMS mirror.
