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…
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…
