Threshold voltage is the gate-to-source voltage at which a MOS transistor forms a conductive channel and begins to conduct appreciable current between source and drain. It appears in transistor datasheets, SPICE model cards, process design kits, and circuit simulation reports for digital and analog blocks, where it shapes logic levels, drive current, and timing margins in both front-end and back-end design stages.
Threshold voltage occurs in device datasheets, compact model documentation, and PDK reference manuals. It also appears in parametric test programs where threshold voltage is measured across process corners and temperature. Translators must keep the term consistent between design and test contexts, and preserve units, bias conditions, and sign conventions for NMOS and PMOS devices.
A frequent error is translating threshold voltage as '门槛电压' without noting that the standard semiconductor term is '阈值电压.' It can also be confused with breakdown voltage or diode turn-on voltage. In datasheets and test specifications, this changes the meaning of operating limits and may lead designers to misread device turn-on conditions or reliability margins.
Terminology must stay consistent across datasheets, design kits and patent filings. A single inconsistent parameter can propagate into fabrication decisions or weaken a patent claim, and IP confidentiality applies to every document in the chain.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
