The architectures and algorithms for a lightweight self tuning engines are explored for improved transient performance against process and passive variations. Reliability aspects of the different on-chip voltage regulators are further explored to study the effects of voltage stress on transient performance and efficiency. A prototype test-chip with an IVR and all-digital self tuning engines to enhance transient performance of the digital load, an AES encryption engine is developed. A specification to GDSII layout automated tool flow for on-chip voltage regulators is also developed to reduce the overall design time. On-chip voltage regulator architectures and corresponding time domain, frequency domain and efficiency models are explored for building the front end of the automated tool flow. A back end physical design flow and an design space pruning based optimization flow are also proposed for the automated tool flow to converge to designs optimized for specific targets. Additionally, a fully synthesized and flexible precision IVR architecture has also been developed to facilitate easy integration with the auto-generation tool flow and improve transient performance.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Design Methodology for Reliable and Energy Efficient Self-tuned On-chip Voltage Regulators "}],"uid":"28475","created_gmt":"2020-08-10 17:49:15","changed_gmt":"2020-08-10 17:49:15","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-08-14T17:00:00-04:00","event_time_end":"2020-08-14T19:00:00-04:00","event_time_end_last":"2020-08-14T19:00:00-04:00","gmt_time_start":"2020-08-14 21:00:00","gmt_time_end":"2020-08-14 23:00:00","gmt_time_end_last":"2020-08-14 23:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
