Buffer amplifiers have unity gain.

Chemical additives and agents include a wide range of materials added to polymer resins, paints and coatings, or adhesives to modify specific processing or end-use properties.

Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current.

RF amplifiers are devices that accept a varying input signal and produce an output signal that varies in the same way, but with larger amplitude.

Buffing and polishing services perform smoothing operations that change a metal's surface appearance.

Buffs, bobs and buffing wheels are used to hold finishing compounds and polish parts made of metal, plastic, ceramic, glass, wood, stone, silicon, or optical materials.

Amplifier and comparator chips are board-level components for amplifying voltage, current, or power.
