Abstract :
Common issues of designing analog circuits in a CMOS mixed-signal environment are summarized. Effects of power supply noise and regulation, substrate noise, cross talk, and layout and floor planning are briefly discussed and a condensed description of proposed solutions are presented. In addition, process scalability for analog circuits built in a mixed-signal chip is reviewed. Design of analog circuits with ability to scale into different CMOS technologies are often neglected in a mixed-signal design which typically culminates in major modifications, or a complete design change for the analog blocks when a the process is changed
