Many commercially available headphone amplifiers utilize design topologies such as Class AB, Class D and Class G and are found in the output stage of ICs such as DACs and codecs. Key criteria in ...

Before jumping into a discussion of amplifiers and signal-conditioning circuitry, it is worthwhile to quickly review strain gauges. By definition, “strain” is an alteration due to an external force. A ...

Current differencing transconductance amplifiers (CDTAs) provide a versatile platform for signal processing in contemporary integrated circuits. By converting differential input currents into ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

Aeva ® (Nasdaq: AEVA), a leader in next-generation sensing and perception systems, today announced the development of a new high-power semiconductor optical amplifier (SOA) delivering industry-leading ...

General-purpose amplifiers (GPAs) can be thought of as the "RF glue" in wireless systems. Although they're simple in design, these amplifiers must boost RF signals to acceptable levels. They also must ...

Phase sensitive or lock-in amplifiers can extract low level signals in the presence of relatively high noise and, recently, there has been growing interest in their use in portable or embedded ...
