I’m writing this circuit, but I can get the output of A0
wired to the input A2.+
, and at the output $V_o$ I can’t get the label above the scope and can’t change the signal at the scope. I have tested with
\ctikzset{bipoles/oscope/waveform=square}
\draw (7,-3) node[oscopeshape,fill=blue](O){};
based on the CircuiTikZ manual 1.4.13 section 4.6.1.1 Oscilloscope waveform.

Update
As noted by js bibra, I was misspelling some keywords, but then at compilation it reports these errors:
! Package tikz Error: Cannot parse this coordinate.
\draw (A0.-) to [short] ++ t
o [C=$C2$](-7,-5.025) -|(-7,0.5){};
! Package pgfkeys Error: I do not know the key '/tikz/circuitikz/bipoles/oscope
/waveform', to which you passed 'square', and I am going to ignore it.
! LaTeX Error: The font size command \normalsize is not defined:
there is probably something wrong with the class file.
ras-down
instead ofra-down
in certain placesto[] ++ to[]
--- you missed a coordinate there, liketo[] ++(2,0) to[]...
. The second one is because you probably have a too old version (see tex.stackexchange.com/q/524328/38080). The last one is probably a secondary effect of some other error...
