electronics - How does a NOT logic gate work? -

as know, in computer architecture if there electricity, value 1, otherwise 0. right except not gate. i'm not here inquire how works, want know how returns 1 if input 0. if don't allow electricity flow input, how outputs electricity? there special in gate produces electricity?

in general, yes, logic gate have separate powerfulness supply logic input. if not gate has input of 0, can provide positive powerfulness supply (vcc) output, logic 1.

a not gate drawn 1 input in order simplify logic diagrams. wikipedia has collection of drawings of actual circuit design on inverter page.
