Analog IC’s are utilized in Industrial, medical, consumer, computer, and communications applications. Analog design is more concerned with the physics of the semiconductor devices such as gain, matching, power dissipation, and resistance.
Fidelity of analog signal amplification and filtering is usually critical and as a result, analog ICs use larger area active devices than digital designs and are usually less dense in circuitry. Analog IC design also has specializations in power IC design and RF IC design.
