What is the difference between vt classes in a library ? What factor do they change to change the threshold voltage (vt) ?
What is MTCMOS ? Any Docs on that ???
What is the difference between a mixed mode process and a normal cmos process - for example IBM has 3 variants of the 90 nm cmos - low power(lp) , mixed mode(rf) and logic cmos (sf)
to change the Threshold voltage Vt, Gate oxide thickness is changed. lower the Vt, higher is threshold; but fast transistor switching
MTCMOS - Multi Threshold CMOS (Mixed Vt design)
Mixed mode process : GDS will contain transistors with different threshold voltages
Normal CMOS process: all the transistors in the design uses same threshold voltage
