The converter may selectively couple, using low-voltage switches, a selected input network of two or more input networks to a virtual ground node, and a selected feedback network of two or more feedback networks to a transconductance stage input. The selected input network and selected feedback network together define a respective input signal amplitude range. The converter may also controllably adjust an AC gain of the converter to match a DC gain of the converter, and selectively couple non-selected input networks to signal ground. Output referred integrated resistor thermal noise may be reduced to a desired value by lowering the value of the transconductance stage coupled across the input of the converter (through an input resistance) and the virtual ground node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid state wideband high impedance voltage converter","description":"A front-end converter circuit may allow devices, e.g. oscilloscopes and digitizers, to receive input signals having a wide range of possible amplitudes while maintaining a high standardized input impe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9755496","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.
