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…
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…
I needed to draw a timing diagram for a mixed signal class I took. I found Timing Editor The problem I was solving is shown below in the image. It's rather tedious to figure out. You have to remember that once a gate capacitance is charged up it ideally holds 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…
Research Links Circuit Envelope Simulation with Agilent ADS Agilent ADS has several features that set it apart from other design packages. It has nonlinear and "cross frequency" capability. Envelope simulation is where you want to see the envelope of an RF signal. I suspect ADS will become much easier to Read more…
