Analog Electronic Circuits Course background and motivation

  • Analog (continuous-time) signals

– Continuous flow of information – Data derived from signals parameters: shape, amplitude, frequency – In Digital the info is discrete and finite

Analog Electronic Circuits Course background and motivation

  • We live in an ANALOG world (still…)
  • The digital Revolution:

– Simple designs, compact, scalable, upgradable, communication, fast time- to-market

  • Any link to the “real world” needs interface

– Computers, Mobile, Audio, Video, Communication

  • $$$ The bottom line $$$

– Electronics hardware engineers, in particular mixed-signal (analog) are top earners with longest prospect across the board of hi-tech industry
