What is the significance of normalized data in NMOSFET parameter extraction?

AI Thread Summary
Normalized data in NMOSFET parameter extraction refers to adjusting measurements to a standard width, which allows for consistent comparisons across devices. In this case, the Id data normalized to w=1μmeter means that to extract the actual Ids for a device with w=10μmeter, the value should be multiplied by 10. Low-field mobility (μ0) is not constant across all NMOSFETs; variations can occur due to factors like fabrication processes and material properties, leading to discrepancies between default and extracted values. The BSIM guide's default value serves as a general reference but may not reflect specific device characteristics. Understanding these concepts is crucial for accurate NMOSFET analysis and modeling.

Hey! I'm doing a lab assignment and need some guidance.

i have measurement with L=1μmeter and w=10μmeter, but the id data is normalized to w=1μmeter, what does it mean?

do I need to get Ids "un-normalized" for extraction, like Ids*1e-6= new Ids


the second question is about low-field mobility, does the low-field mobility μ0 equal for all NMOSFETs? the BSIM guide Iam using have default value is 670 cm^2/Vsec for NMOSFET. but the extracted value is like 200cm^2/Vsec, I'm confused.

I don't know if this is the right sub-forum for posting those questions, please moderators change it to appropriate sub-forum if needed.

Thanks in advance

I'm sorry you are not finding help at the moment. Is there any additional information you can share with us?
 
The general MOSFET equation is Id = mu Cox W/L ((Vgs-Vth) Vds - Vds^2/2). This is the W/L they are referring to.
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
