I think that this arises from the Input Power limitation of the Device
since in CMOS devices the power consumption is due to switching, such large switching with high overshoot, consumes a large power which can not be dissipated
I think there is no tough rules that base must be small.
Base in comparision with emitter is smaller and has less doping.
The only thing that are important (i give you an example of pnp transistor ) is that the lengh of emitter must be longer than the lengh that are needed to combine electrons...
Re: please help
It strongly depends on your circuit for example in some circuit like the ones with diodes if you put your probe inversly you with get another voltage
so it depends on your linearity and non-linerity of your circuit
if you put a figure of your circuit here i will tell you the...
Re: What is fuzzy logic?
i suggest you to take a glance at the begining of many fuzzy logic ebooks uploaded there like" Fuzzy Logic for Embedded Systems Applications"
do search at eda ebook you will find more
