If you need a voltage reference when doing energy harvesting it is very helpful have a band gap reference that uses very little current. Â This topology uses “Self Cascode Mosfet” Â abreviated as SCM. Â The LTSPICE design uses 4.5 nano Amperes and outputs a 0.6 Volt reference voltage.

Lab Document: Extraction of MOSFET Parameters using 4007 Array My PDF Solution – Warning Will Robinson: I never get 100% correct! The following two measurements are where the MOSFET is in saturation and use the 8if method to nd ISpecific. In this case because we are looking into the MOSFET source Read more…
I have wanted to use the SPICE MOSFET model more closely for while and found this guide: MOSFET Simulation Guide With it I hope to be able to finally crack the problem of changing the threshold voltage. Up till now when I have gone into the text of the model files for MOSFETs Read more…
If I use LTspice do I have to modify the SPICE models that I download from MOSIS? The models I download from CMOSedu.com work great with LTspice but I want to try some other technologies. Yes, but you will have to change the Change Level = 49 to Level = 8 for the BSIM3 Read more…
Report Delivered for this project here This entry records the steps taken after the above report was delivered. BookSeeBookSee TN3 was too long previous to this fix. Thus TN5 was not shutting off sufficiently and drawing too much current off of the current mirror. Next Steps: Redo startup transient analysisResearch Read more…
