Why Analog?* Digital Communications* Disk Drive Electronics* Wireless Receivers* Microprocessors and MemoriesHigh-speed digital design is in fact analog design!Analysis and Design of Analog Integrated CircuitsUESTC Luo Ping2010/9/68ITRS----International Technology Roadmap for SemiconductorsDiscrete AnalogDigitalMixedAnalysis and Design of Analog Integrated CircuitsUESTC Luo Ping2010/9/69 Components sharing the same substrate in close proximity can be used as a tool for component matching design3. Characteristics of IC design ----IC compares with PCB---- It is impractical to breadboard the integrated circuit design The geometry of active device and passive components in integrated circuit design are under the control of the designer Designer must turn to computer simulation methods to confirm the design’s performance Integrated circuit designer is restricted to a more limited class of components that are compatible with the technology being usedAnalysis and Design of Analog Integrated CircuitsUESTC Luo Ping4. Analog Design Challenging* Digital circuits deal primarily with speed and power tradeoff * Analog circuits deal with multi-dimensional tradeoff of speed, power, gain, precision, supply, … * Due to speed and precision requirements, analog circuits are much more sensitive to noise, crosstalk, and other interferers * High performance analog circuit design can rarely be automated - typically require hand-crafted design and layout2010/9/610Analysis and Design of Analog Integrated CircuitsUESTC Luo Ping4. Analog Design Challenging * Analog circuits are much more sensitive to second-order device effects * Modeling and simulation of analog circuits is still problematic, requiring experience and intuition* Economic forces require the development of analog circuits in mainstream digital processes* Economic forces pushing the integration of analog and digital functions onto a single substrate2010/9/611Analysis and Design of Analog Integrated CircuitsUESTC Luo PingDigital Design Process: Specification System Design Ckt. = Auto generated System Simulation Ckt.
