Not only are they made of analog devices, but at the speeds things have been 
running at for the last 20 (maybe 30) years, they often behave like analog 
devices. Things like transmission line theory, crosstalk, oscillation, etc are 
all important design considerations.

Subject: Digital circuits and analog devices

So I have this memory of a set of law promulgated by an engineer at DEC, one of 
which was something to the effect that 'all digital circuits are made out of 
analog devices'. However, my memory doesn't recall where I saw this, and my 
Google-fu is not strong enough to turn it up. Can anyone help?
