An example for the rise time analysis, a simulation of NMOS structure using an open drain buffer, and the 2N7001T device was done as shown in Figure 4. The open drain output with a pull-up resistor of 1-kOhm driving a 30-pF cap load resulted in a rise time of about 73ns as shown in ...
WebSep 26, 2024 · The reason some suggest not to use low Ic/Ib ratios (i.e. they warn you against putting the BJT in deep saturation) is because the deeper the saturation, the larger the stored charge in the base, the longer the turn-off time (like a diode). That's why TTL … 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!
