Vcc??

Hey everyone, I'm new to the world of electronics and am trying to figure out how to read a schematic. I can see that there are alot of references to Vcc on a particular schematic I'm looking at? What does the Vcc mean? Does this refer to the positive side of a power supply and GND refer to the negative??

Thanks for your help!!
 
u r right

hi
u were right abt the vcc.its the supply voltage and can be called the saturation voltage ie the max value which can be obtained from the particular device neg supply need not neccesarily refer to gnd.its just
a point for lower potential.this might right now sound a bit confusing
ull under stand with experience.check out dual power supply ,i think u ll get an idea of i am trying to convey.
bye
 
Hi,
In transistor based circuits the power supply connected to the collector of a transistor to bias it is called Vcc (Collector voltage). Similarly in FET(Field Effect Transistor) based circuits you will find Vdd instaed of Vcc. In FET instead of collecter there is a pin called Drain and the supply voltage applied at Drain in called (Vdd).
Also in transistors the reference point is taken as ground (0v but not necessarily be). In FETs it is termed as Vss (Source voltage)

Hope you got the answer.

Now you'll also have a question that even IC based circuits have Vcc and Vdd. Thats because ICs actually contain Transistors and FETs in them. Thats the reason!
