The second LC network includes a capacitor bank including capacitors in parallel including switches for switching (selectable capacitors) and an inductor L3 in parallel to the capacitor bank. Values of L2 and C2 provide a low frequency point fL which the LC network is overall capacitive, and in a frequency range between fa and fb above fL with only a portion of selectable capacitors selected a capacitance of the capacitor bank and value of L3 results in an overall impedance for the second LC network that is capacitive between fa and fb and inductive elsewhere."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasound lens cleaner driver with frequency selectable oscillator","description":"A frequency selectable driver circuit (driver circuit) includes a current drive transistor between a first and second node for driving a frequency selectable oscillator (FSO) coupled therebetween that","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667191","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.
