Transit vs Unity Gain Frequency of a MOSFET

I have read over the years that term transit frequency is associated with both MOSFETs and BJTs, and its the frequency at which the current gain becomes unity. It's usually understood as a figure-of-...

Transit vs Unity Gain Frequency of a MOSFET

Transit frequency of a MOSFET is the frequency at which the small-signal current gain drops to unity while the source and drain are AC grounded. Unity gain frequency doesn't mean anything unless you ...

Transit vs Unity Gain Frequency of a MOSFET

According to this answer, the unity gain frequency and transit frequency have the same definition but in difference context. We mostly use transit gain with discrete BJT by looking at the frequency ...

How is gain changed in this op-amp integrator?

When we speak about the "gain" of an active circuit, there must be one fixed DC operating point around which a small signal can swing. Because the input signal has no DC component, the only ...

Gain of a negative feedback circuit (problem)

By your own statement, each FET stage will have voltage gain: $$ A_1 = A_2 = A_3 = -g_mR_L $$ Each stage multiplies the voltage output of the previous stage, so if the first stage FET has gate voltage ...

Gain of a negative feedback circuit (problem)

Re-draw the schematic, using voltage controlled voltage sources as FET models. The voltage controlled voltage source (VCVS) G is an only component of the hybrid-pi model, a small-signal FET model, in ...
