ABSTRACT:
A piezoelectric structure receives input from a voltage source to generate polarization and output voltage. Two surfaces are formed on the direction normal to the polarized direction. One surface has an input electrode electrically connecting to the voltage source and an output electrode to output voltage. Another surface has a ground electrode. The distance between the input electrode and the ground electrode is different from the distance between the output electrode and the ground electrode. Through the height difference of the two electrodes, the step-up and step-down ratio can be altered.
