- trsohmers 9y agoI know a lot of people using LVT transistors in 28 and 16/14nm processes, including relatively low power (mobile and embedded) designs. I personally have used LVT variant SRAM blocks for both our 28nm and 16nm designs, and ULVT cells manually placed for critical path for Neo's FPU for our 28nm chip.
- deepnotderp 9y agoI should've rephrased: I don't know of anyone* who uses ULVTs exclusively, to answer the parent of using ULVTs to increase speed. * Okay, I know of some people, but their design is different.
- Symmetry 9y agoI'm not surprised, though I don't have a good sense of what the exact numbers are.
- deepnotderp 9y agoLeakage diff @ 125 degrees celsius is about one order of magnitude.
