Abstract
The use of piezoelectric resonators (PRs) as energy
storage elements in dc–dc converters has captured considerable
interest, in part due to the ultra-thin planner form factor,
excellent frequency/volume scaling properties, and high cou-
pling and quality factors offered by PRs. Traditional PR-based
converters, however, exhibit performance diminishment at low
voltage conversion ratios (VCRs), rendering them less appealing
to applications that require low VCR operation. This article
presents a dua
