I've represented an IC circuit using circuitikz, but it's a bit too rough to what I prefer. In particular I would like to use relative coordinates in this case and connect them to the ``IC device'' so that I don't have to guess where to place components. I would also like to scale the figure and maintain the integrity of the circuit. (Remove scale = 1.4 to get the unbroken circuit)
Any suggestions?
