Integrated Circuit Design

IC design or Integrated Circuit design is a sub-category of electronic engineering, encircling the specific logic and circuit design techniques needed to design integrated circuits, or ICs. ICs comprise small-scale electronic components such as resistors, transistors, capacitors, etc. fabricated into an electrical grid on a monolithic semiconductor.

Digital and analog IC designs are the two wide categories of IC design. Components like microprocessors, FPGAs, different memories (such as: RAM, ROM, and flash) and digital ASICs are produced by digital IC design. Digital design’s main focusing points are logical rightness, ensuring maximum circuit density, and placing circuits to ensure efficient routing of clock and timing signals. Power IC design and RF IC design are the fields in which Analog IC design has specialism. Analog IC design is used in the design of phase locked loops, op-amps, oscillators, linear regulators and active filters. Analog design bothers about the physics of the semiconductor devices like resistance, gain, power dissipation and matching. Integrity of analog signal amplification and filtering is generally critical and for this reason, analog integrated circuits use comparatively bigger area active devices than digital IC designs and commonly not so much dense in circuitry.
