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 Cons 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
