A slightly more robust solution is to load the attached module instead of 
t-tikz. (It also patches \usetikzlibrary). However, I cannot figure out 
what is the expected catcode of & inside a tikz \matrix. So, you will 
still need to use amserand replacement=\&.

Note that this sets the catcode of ! to other (as expected by tikz). In 
the past, circuittikz has some troubles with the catcode of !.
