Why Analog? • Digital electronics: • High precision • incensitive to process variations, supply voltage change, temerature, interference, and aging • Programmability/configurability • DSP algorithms can be changed easily in software Analog circuits could seem obsolete, but analog circuit designers are in demand. Why?
Why Analog? • Analog electronics • Need to interact with the physical world, which is analog!!!
Why Analog? • Digital Communications • copper wire • optical
Why Analog? • Wireline communications • E.g., ADSL
Why Analog? • Storage systems
Why Analog? • Wireless receivers
Why Analog? • Sensors/transducers “Single-chip CMOS image sensor for mobile applications,” K. Yoon, C. Kim, et. al, ISSCC 2002
Why Analog? • Microprocessors and memories Pentium 4
Why Integrated? • Huge numbers of components driven by functionality demands • Memory chips: billions of transistors • Microprocessor: tens of millions of devices • Moore’s law: number of transistors doubles every 1.5 years
Why CMOS? • Pros • Can implement both analog and digital circuits • Mixed-signal design • Low cost • Only dynamic power dissipation in digital circuits • Continued scaling • Cons • Slower than BJTs • Noisier than BJTs
