Abstract
A device includes: a piezoelectric transducer; a field effect transistor (FET) configured to provide a sub-threshold conduction path for leakage current across the piezoelectric transducer; wherein the FET comprises a gate; wherein each of a width and a length of the gate has a size in accordance with the sub-threshold conduction path being configured to substantially maintain an input voltage to the piezoelectric transducer across a path of the leakage current of the piezoelectric transducer.
