Described is also a voltage regulator which comprises: mutually coupled on-die inductors for coupling to a load; a bridge, coupled to the mutually coupled on-die inductors, including a low-side switch and a high-side switch; a PWM controller for controlling the low-side and high-side switches during a first load current; and a PFM controller for controlling the low-side and high-side switches during a second load current, the second load current being smaller than the first load current, the PFM controller comprising: a comparator for comparing output voltage of the load with a reference voltage; and a first PDL coupled to the comparator for determining turn-on duration of the high-side switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low power high frequency digital pulse frequency modulator","description":"Described is an apparatus that comprises: a programmable delay line (PDL) to receive a pulse-width modulation (PWM) signal as input and to generate a first output; a selection unit operable to provide","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9711108","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
