There are no linear components at this level.

In particular you will have to deal with parasittic resistance across
capacitors but usually the "series trick" will do:


    ---+----/\/\/\------+---------
       |                |
       |              -----
       |              -----
       |                |
       -----/\/\/\------+
                        |
                      -----
                      -----
                        |
    --------------------+---------

(The point here is that there is no DC over the top cap, so there
is no current through the parassitic resistance.

Never attribute to malice what can adequately be explained by incompetence.
