gmoverid
Yes, basically when you use 1st order equation, the ideal one is gm/Id = 2/Veff. However, if you use realistic model to simulate, it is far from ideal. Basically you can use SPICE to sweep the Vgs and calculate gmoverId. Then plot gmoverId vs different Vgs values and you can see that...
what is thermometer code
Hi,
The digital thermal code for a flash ADC assembles that of a thermometer (obvious eh? =)). Unlike binary coding or other coding methods, the '1's in the output code increases as the input voltage increases. e.g.
0V -> 00000
0.1V -> 00001
0.2V -> 00011
0.3V ->...
Hi everyone,
I want to write a OCEAN script to plot the gm/id vs. Vgs - Vt of a NMOS. However, there are 2 problems which I encounter.
1) What's the command to get gm/id of the nmos?
2) How do I get Spectre to plot Vgs - Vt as the x-axis and set Vgs-vt as the variable instead (not just Vgs)...
