...faced with several ways to configure a basic circuit, in meeting some performance challenge, it often pays to use the simplest possible form. Of course, (if) we can't create new circuit forms, from scratch, in this way, only choose from pre-existing possibilities. The origination of topology is a daunting aspect of analog design, and the chief reason why many find it difficult... -- Barrie Gilbert
