Signal amplifiers are used in a variety of fields by adopting circuit systems suited for respective fields. Audio signal amplifier systems are used in conferencing systems, sound amplifying systems in halls or in the open air and in hearing aids. A D-class signal amplifier of low power consumption is mainly used as a power driving circuit for driving a speaker. Optical waveguide signal amplifiers comprise a glass, optical waveguide fiber doped with an optically active material. Such amplifiers are intended for use in long distance, optical fiber, telecommunications systems. Variable gain voltage signal amplifiers may be employed in electronic circuits that read signals or information stored on a disk or diskette. Controllable gain signal ampliifer circuits are widely used in television receivers to control volume, color saturation, tint and constrast functions. A broadband signal amplifier is suitable for use in measuring apparatus, communication apparatus, medical apparatus, high-definition television circuits, circuits for color graphic display devices and computer monitors, and, for amplifier circuits for amplifying signals sampled at high sampling frequencies in digital apparatus. Differential signal amplifiers amplify a differential signal to form an amplified differential output signal and can be used for a variety of purposes and within different types of circuits. Typical uses of differential signal amplifiers include using an amplifier with a gain greater than 1 to increase the amplitude of the input signal. Other uses include using the amplifier as a buffer between circuits. Applications for differential signal amplifiers include uses within current mode logic (CML) circuits.
