WebMay 7, 2024 · With a relatively sharp signal at the base of the transistor, can I assume a high-to-low transition at the 2N3906's output to have a delay of "storage time" + "fall time" = 225+75=300ns. What about the rise time? Isn't the rise time determined by the load resistance? If so what does the "rise time" of the transistor mean? Thanks in advance!

WebWhen BJT’s are used as load switches, they are used in two modes: Cutoff and Saturation. Consider figure 3 below. As previously stated, I C = βI B. So, if I B = 0, then I C must also be 0. In this state, the transistor is in cut-off mode. WebApr 24, 2024 · 91. 1) Charge neutrality is a must or the bjt would cease to function.

Its switching characteristics are specified in relation to external load circuit … WebThe rise in V gs during t 2 (Fig. 2) is brought about by charging Cgs and Cgd. During this time Vds does not change and as such C gd and C ds stay relatively constant, since they vary as a function of V ds. At this time C gs is generally larger than C gd and therefore the majority of drive current flows into Cgs rather than into Cgd. This ...
