Abstract: This study presents a novel triple‐step bias‐flip rectifier with a post implementation calibration (PIC) scheme to address both the need for a general‐purpose adaptable piezoelectric energy harvester (PEH) interface circuit (PEHIC) and the PVT‐related issues while maintaining acceptable efficiency and a smaller inductor. Due to the PIC, the proposed circuit is adaptable to various piezoelectric materials and inductors. Using a 100‐µH inductor, a 180 nm standard design kit, and an energy investing (EI) scheme, the proposed rectifier achieves a bias flip efficiency of 100%. Without EI, the proposed circuit achieves the recently reported high bias flip efficiency, that is, ɳflip, in the literature with a considerably smaller inductor. According to simulation results, the improvement of the designed circuit relative to the full bridge rectifier (FBR) falls within the scope of 2–3.8. Postsimulation calculations revealed that the figure of merit of adaptivity, that is, FoMadaptivity, of the proposed circuit is approximately 83. [ABSTRACT FROM AUTHOR]
