I have a Question on simulating a grounded substrate via using MPIE and solving with MoM. How is the z-directed basis function actually "grounded"? Is it just taken care of with the planar satisfied medium Green's function? I have a simple code and when I just add a z-directed basis function...
I wrote my own MoM closed box code to solve symmetrical microstrip discontinuities. I use even (1,1) and odd (1,-1) mode excitation and extract the s-parameters from the result current distribution. I am trying to find our what excitation should be used and the corresponding s-parameter...
I best book I have read on MMIC design is "Microwave Transistor Amplifiers: Analysis and Design" by Guillermo Gonzalez. For passive microwave circuits I recommend "Microwave Engineering" by David Pozar.
There are a few things that I am not sure about with your schematic. First, what are the gates of your two lower transistors tied to? Are they just two devices in parallel in which the gates are tied together as well? Second, your top transistor has it's gate tied to the Vdd rail voltage...
The drain current will be the same for both transistors. Yes, typically you want both transistors in the saturation region. Yes, the cascode cell will be unstable. You will have to stabilize the cascode cell and there are many approaches and techniques for doing this. As for the current...
No, for MMIC design you will need a strong background in EM. The main difference between analog CMOS design and microwave/millimeter-wave MMIC design is that in analog CMOS design you are design in terms of voltages and currents at nodes. In microwave/millimeter-wave MMIC design, you are...
I would like to get a method of moments (MoM) code in preferably Matlab or some other language that shows in detail how to solve and extract s-parameters of a simple structure like a microstrip line. I have used many EM tools that can solve this problem so I am not looking for software that...
