Encircle a formula with arrow pointing from the circle

Is there perhaps a package that already does something like this?
In THIS topic encircling a formula is given, but I don't understand the syntax to modify the 'circle' to have an arrow point outward from somewhere.
The end goal is to have something like this.
I tried to use the example given in the linked topic as a base
documentclassarticle
usepackagetikz
makeatletter
newcommand*encircled[1]relaxifmmodemathpalette@encircled@math#1else@encircled#1fi
newcommand*@encircled@math[2]@encircled$m@th#1#2$
newcommand*@encircled[1]%
tikz[baseline,anchor=base]node[draw,circle,outer sep=0pt,inner sep=.2ex] #1;
makeatother
begindocument not important at the moment
enddocument
There are a lot of embellishments that have something to do with preserving proper formating or some such. The core of the problem is to modify the node[...] bit which results in a circle with an arrow pointing out from it, but I feel that's a dead-end.

Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting withdocumentclass...and ending withenddocument.

@Alvin_Lepik: Do you want the whole picture in TikZ or just the circled part – I'm confused, since I think I didn't understood your question … I thought you want a command which produces a circles node from which is pointing an arrow out and that all as abaseline-TikZ picture.

Judging from the various comments I think that what you need is thetikznodeapproach where the positioning is done by TeX implicitly; see the second modified example in my answer.

The best approach depends on whether your sketch is meant as a single image---in this case use a single tikzpicture environment---or whether the items appear mixed with text on a page---in this case use the tikznode command from this post. Here are examples for both situations. Note that you have to run LaTeX twice on the second example.
Everything in a single picture: The position of the elements can be specified explicitly relative to each other.
documentclass[border=1pt]standalone
usepackagetikz
usetikzlibrarypositioning
begindocument
begintikzpicture
node[circle,draw](fx)$f(x)$;
node(a)[below right=of fx]$a$;
draw[->] (fx) -- (a);
endtikzpicture
enddocument
Graphical elements as part of text: The position of the elements is defined implicitly by the typesetting engine that positions the elements.
For examples of the use of tikznode see e.g. Breaking numbers Simple addition, How to add arrow in equations and matrix? or how can you point the head of an arrow from tikzpicture to an equation in LaTex?.
documentclassarticle
usepackagetikz
newcommandtikznode[3]%
tikz[remember picture,baseline=(#2.base)]
node[minimum size=0pt,inner sep=0pt,#1](#2)#3;%
begindocument
[ fracg(x)tikznode[circle,draw]fx$f(x)$
=fracg(x)tikznodea$a$
]
begintikzpicture[remember picture,overlay]
draw[->] (fx) edge[bend right] (a);
endtikzpicture

I apologise for ambiguity, the downpointing arrow simply shows the output of command. Regardless, the question is answered :)

you're right, overlapping was due to a box environment in which I was using the circling.
