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 ...

A variety of headphone amplifier types are available, but little guidance is provided in their selection. This article discusses the types available, and covers their relative strengths and weaknesses ...

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

We believe that changes will force amplifier manufacturers to make a greater variety of products having characteristics tailored to the specific application. We've already seen that as voltages drop, ...

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 ...

This sponsored post takes a look at Intel’s tools, like Intel VTune Amplifier, for improving application performance on the latest processors. There are many tools out there that will analyze an ...

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 ...
