The signal transmission circuit includes: an input circuit, configured to generate a first test signal in response to a first control signal and a clock signal; a transfer chain, including multiple stages of serially-connected transfer circuits, where adjacent transfer circuits in the transfer chain are connected via a through silicon via (TSV), the transfer circuit on one end of the transfer chain is connected to the input circuit, and the multiple stages of transfer circuits transfer the first test signal in stage by stage in response to the clock signal; and multiple signal output ends, where a first test signal input end of each stage of transfer circuit is correspondingly connected to one signal output end. The signal transmission circuit improves the effective utilization rate of a chip in an IC having a TSV test circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal transmission circuit and method, and integrated circuit (IC)","description":"A signal transmission circuit and method for testing an integrated circuit (IC) are disclosed.
