I'm trying to use the code invert in circuitikz, however I'm getting an error with it, other bipoles work well. How can I invert/ flip it?

Thanks!

\documentclass[border=5pt]{standalone}
\usepackage{circuitikz}

\begin{document}

\begin{circuitikz}
\ctikzset{bipoles/amp/width=0.9}
\draw (0,0) to[amp,t=LNA,l_=$F{=}0.9\,$dB,o-o] ++(3,0);
\end{circuitikz}

\end{document}

    showed image is not produced with provided mwe. sorry, but from your question is not clear (to me), what you like to obtain. reversed direction of amplifier? – Zarko Aug 25 '18 at 22:55
  • Thanks for your help. When I use invert like in your example I get the error Package pgfkeys Error: I do not know the key '/tikz/invert' and I am going to ignore it. Perhaps you misspelled it. This happens on both my own setup and online platforms like overleaf. – John Miller Aug 26 '18 at 7:58

    apparently overleaf has old installation of the circuitikz package. with the recent version the miktex package it works. function invert is documented in the package documentation (version 0.8.3 (2017/05/28) ) on page 43 in the section 5.8 Mirroring and Inverting. try to upgrade your installation of latex. – Zarko Aug 26 '18 at 8:31
  • I changed the package locally now it works on my machine. Thanks for your help! – John Miller Aug 26 '18 at 9:41

your mwe produce the following figure:

than try the following:

\documentclass[border=5pt]{standalone}
\usepackage{circuitikz}
\usepackage{graphicx}

\begin{document}

\begin{circuitikz}
%\ctikzset{bipoles/amp/width=0.9}
\draw (0,0) to[amp, invert,                 % <---
                    mirror,                 % <---
                    t=\rotatebox{180}{LNA}, % <---
                    l_=$F{=}0.9\,$dB,o-o] ++(3,0);
\end{circuitikz}

\end{document}
