I am trying to draw the circuit below, however I am having difficulty in drawing the connections to the supply rails. I've abused the sground node since it is the same as the typical symbol for power supply connections.
As you can see, the
For the node labelled VSS, I can use the sground node without any problem, but for nodes labelled VDD, I have to invert it, which I am doing by setting the y-axis scale to -1. This has the side-effect of inverting the associated label:
(0, 10) node [sground, yscale = -1] () {$V_{DD}$}
How can I achieve this without inverting the text?
