Fmax is the frequency where unilateral gain (U) becomes unity, or zero dB. "U" was developed by Samuel Jefferson Mason, (and also known as Mason's Invariant", the concept was published when transistors were having their third birthday party (reference at end of page). It is still one of the most important … See more We'll add to this later. FT is the "transition frequency" where current gain goes to unity (zero dB). See more S. Mason, "Power Gain in Feedback Amplifiers",Transactions of the IRE Professional Group on Circuit Theory, Volume CT-1, Issue … See more WebSep 10, 2008 · DC and Bias Point Simulations > FET Fmax vs. Bias. Description. This simulates the maximum frequency of oscillation (the frequency at which the maximum available gain drops to 0 dB), versus bias voltage, for a particular value of VDS. It should help you determine how high in frequency a device can be used. Needed to Use …

WebAug 15, 2013 · This will help to find FT versus Bias ( I have used BJT in my case but you can change ) For fmax, the approximated fmax equation would help you but it's just an approximation and sometimes it may be very different than reality. WebAug 8, 2008 · The simulation results are shown in Figure 2. The difference in the results is that the low frequency bipolar transistors current gain is limited by the base current, while the MOS transistor current gain is not limited. Note, in advanced node processes, MOS transistors do have significant gate leakage and the plot for the MOS transistor would ... reaching beyond the net in volleyball
