2. When we talk about 45nm, 32nm node, what physical parameter of a CMOS are
we talking about? The width?
3. Data rate of an ossiliscope is given, how do you calculate the resolution?
4. N type and P type, which one is stronger?
可能有的题描述的不是很准确，但还是希望大家给点意见，感谢感谢。 | o********s
发帖数: 66 | 2 我来试试：
1.Vds？channel width？fanout？是不是应该是inverter的速度？
2. 应该是工艺能做到的最小沟道宽度。
3. no idea
4. n type? 因为电子迁移率更高? | l*****x

4 应该是P-type，因为都做在N-well里，可以有效去除substrate propagated noise，
更稳定

发帖数: 957 | 4 1. the speed of the transistor is determined by the size, usually the width
of the transistor. bigger size is faster
2. the minimum length of the transistor
3. no idea
4. it depends on the process. 45nm and 28nm are different.
I will try to look the #3 later see if I know something
are
resolution?

temperature,doping,thickness
2. When we talk about 45nm, 32nm node, what physical parameter of a CMOS are
we talking about? The width?
minimum length
3. Data rate of an ossiliscope is given, how do you calculate the resolution?
resolution = bit rate / clock freq /#channel
4. N type and P type, which one is stronger?
stronger? i don't understand clearly,
may be N type |
