HVT 逻辑门的特点是速度慢,功耗低,因为其阈值电压高,所以需要更高的电压才能打开晶体管。SVT 逻辑门速度和功耗相对于 HVT 和 LVT 之间,因为其阈值电压在标准范围内。LVT 逻辑门速度快,功耗高,因为其阈值电压低,只需要较小的电压就可以打开晶体管。在逻辑综合中,设计人员可以选择使用不同的 HVT/SVT/LVT 逻辑门...
Some technology nodes have a ULVT device as well, depends on the Fab offering the device options. HVT will have a high threshold voltage, hence lower leakage and lower current drive. This directly translates to lower active/dynamic power. The converse is true for the LVT or the lowest VT ...
