The following question has come up in comments: "How do I measure F max for an MOS transistor?" The measurement methodology -- testbench, analysis, calculator setup, stimulus, etc.-- does not change whether you are measuring bipolar transistors

December 7, 2010
There were several questions about measuring transistor f max in comments posted to my previous Measuring Transistor f t and Simulating MOS Transistor f t blog posts. So in this posting we will look at simulating transistor s-parameters and device characteristics

October 6, 2010
Recently there was an inquiry about the methodology for performing the f t (transition frequency) versus Ic measurement described in my Measuring Transistor f t blog post from July 2008: By bid75 on September 8, 2010 I am unable to understand how ft vs

December 18, 2009
Greetings, In the previous appends, we looked at using Shooting Newton Periodic Steady-State analysis to analyze analog circuits. In this append, we will look at using Harmonic Balance Periodic Steady-State, HBPSS, to analyze analog circuits. HBPSS is

June 30, 2009
In " Spectre RF by any other name ...", a non-RF application for Spectre RF's periodic steady-state analysis was introduced. An example of using periodic steady-state analysis [PSS] to simulate the dynamic performance: THD and SFDR, of a

It has been a while since I last appende d , hope you are well! It was a little bit difficult to come up with a subject to write about and then recently I was in a meeting where we were talking about transient noise analysis. A designer was discussing

Simulating MOS Transistor ft
By

on
August 9, 2008
One other question that you might ask is, this approach works for bipolars but what happens when you need to characterize a MOS transistor. Nothing changes, use the same testbench and measurements, see figure 1. In this testbench a MOS transistor is being

So let’s consider a practical example of creating test benches and performing measurements, starting with how to characterize a transistor. A couple of questions to consider before starting are: What parameters do you want to measure? What types
