Integrated circuits are classified into analog , digital and mixed signal . Digital integrated circuits can contain a few thousand to millions of logic gates, flip-flops, multiplexers, and other circuits type in a few square millimeters. The small size of these circuits allows high speed, low power dissipation, and cheaper manufacturing costs compared to that of board-level integration. The digital Integrated circuits, microprocessors, DSPs, and micro controllers work by using binary mathematics to process "one" and "zero" signals. Analog Integrated circuits , work by processing continuous signals. They perform functions like amplification, active filtering, demodulation, mixing, etc. Analog Integrated circuits help circuit designers by having expertly designed analog circuits available instead of designing a difficult analog circuit from scratch. Analog Integrated circuits include sensors, power management circuits, and operational amplifiers Integrated circuits can also combine analog and digital circuits on a single chip to create functions such as A/D converters and D/A converters. These circuits offer a smaller size and a lower cost, however they have to account for signal interference.
