The transistor arrangement includes a control MOSFET in series with a series connected chain of cascaded cells. The control MOSFET and each of said cascaded cells are coupled to the current mirror circuit and each of the cascaded cells includes a pair of MOSFETs arranged to provide a voltage difference including a difference between a gate-source voltage of a first of the pair and a gate-source voltage of a second of the pair."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sample and hold circuit for current","description":"A sample and hold circuit configured to sample a current includes an input node to receive the current, a capacitor coupled with a sampling node and a reference voltage node, switch between the input ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11521693","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.
