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!

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 22, 2024 · The BJT acts as a switch, completing the circuit between the DC supply, the LED and the current limiting resistor, \(R_C\).

It is expressed in volts per microsecond. SR = dVo/dt V/µS It indicates how rapidly the output of an op-amp changes in response to changes in input. Slew rate changes with voltage gain and is normally specified at unity gain. porcelain floor tile beige
