13
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?
14
Why Analog? Analog electronics
Need to interact with the physical world, which is analog!!!
15
Why Analog? Digital Communications copper wire optical
16
Why Analog? Wireline communications E.g., ADSL
17
Why Analog? Storage systems
18
Why Analog? Wireless receivers
19
Why Analog? Sensors/transducers
“Single-chip CMOS image sensor for mobile applications,” K. Yoon, C. Kim, et. al, ISSCC 2002
20
Why Analog? Microprocessors and memories Pentium 4
21
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
22
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
23
Levels of Abstraction
