the I in a circle in IC schematics / block diagrams

yea, so when they say its the quiescent current of the device it means that the indicated circuit schematics can be used to measure the quiescent current of the "device" as a whole, being able to approximate the contribution to its measurement provided by the the stand-by mode of the CMOS IC itsself to zero,allowing the measured value to be considered be the draw of the total circuit?
