Conference paper (2026) - Shunmin Jiang, Tiansu Wang, Patrick Mercier, Sijun Du
This paper proposes an on-chip sigma regulation system for the accurate and power-efficient control of piezoelectric resonator (PR)-based DC-DC converters to address the challenges of conventional off-chip controllers. A zero-standby sigma-mode is implemented for transient response/output power improvement. Peak efficiencies of 91.2% and 90.7% are achieved for the PR converter and the PR-sigma converter respectively. ...
