I dont get one thing though, if we are dealing with digital signals to the transistor base, is it possible for the base voltage to be same as the Vcc?
An example is the PIC, the I/O pin output voltage during HIGH is approximate to the Vdd, which is around 5V. Does this mean that the Vcc should be less than the base voltage of 5V to fully saturate?
All the while through looking at the Q-point analysis, i thought that as long as we have a high base current, we would able to saturate the transistor
