The Analog ICs are designed to process continuous signals and are built using specialized semiconductor processes optimized for performance and efficiency. Common categories include operational amplifiers, voltage regulators, data converters, comparators, and power management ICs.

Unlike digital circuits, analog IC design requires careful consideration of noise, stability, linearity, and temperature variations. Fabrication often involves CMOS, BiCMOS, linear integrated circuits, analog signal processing, operational amplifiers, mixed-signal ICs, analog semiconductor devices and bipolar processes, depending on performance requirements.

Miniaturization, integration of mixed-signal ICs, and advanced semiconductor materials are shaping modern analog IC development. Designers also focus on improving low-power operation, high bandwidth, and precision performance, making these ICs suitable for compact and energy-efficient devices.
