In one embodiment, the novel phantom-powered JFET gain circuit is encased as a standalone box that connects to a microphone on one end and a conventional preamplifier unit or another conventional audio processing unit on another end. In another embodiment, the novel phantom-powered JFET gain circuit is integrated into a portable electronic device or another consumer electronic device with a microphone to provide an earliest-stage gain in a microphone-captured audio signal processing pathway. Yet in another embodiment, the novel phantom-powered JFET gain circuit is integrated into a preamplifier unit and provides the earliest-stage gain in a microphone-captured audio signal processing pathway, prior to additional and conventional signal amplification by the preamplifier unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Integrated phantom-powered JFET circuit module in portable electronic device for creating hi-fidelity sound characteristics","description":"A novel phantom-powered JFET gain circuit that improves audio clarity and linearity, while reducing a high-gain burden, noise, and distortion from a sole usage of a conventional preamplifier, is discl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9668045","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.
