  • Understanding DC Instrumentation Amplifiers
    DC instrumentation amplifiers are simple devices, used to modify signals in some specified way. However selecting amplifiers can be difficult, because specification terminology is neither widely understood nor universally standardized. Users may therefore benefit from a review of current practices.
  • Benchtop and USB-Powered Amplifiers Serve Measurement Applications
    Among the broad array of tools used by designers for stimulating and measuring the performance of their creations, benchtop amplifiers are some of the most basic and useful. Over the last few years, they†TMve been joined by very small amplifiers that take advantage of USB for both DC power
  • How to Monitor Sensor Health with Instrumentation Amplifiers
    By their very nature, in amps are a good choice to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp instrumentation amplifier architecture performs this function with the input stage providing a high input impedance while the output stage
  • RF Power Amplifier Efficiency: Big Challenges for Designers
    impediments to converting DC power into RF power, from losses incurred throughout the signal path, to operating frequency, the inherent characteristics of the device, and others. The result, as an article in MIT Technology Review uncharitably put it, is "a grossly inefficient piece of hardware."
  • About Power Ratings
    the power rating mean something different for a power op amp? In the audio amplifier market there are many definitions for the power ratings of an amplifier but they all relate to the power that can be delivered to the load (speakers) and the rating always relates to sine wave signals to the load. DC
  • Electrical Considerations of Fan Cooling
    The article covers the electrical considerations for connecting the cooling fan of Power Amp Design power op amps to the signal circuits. All of the power op amps currently produced by Power Amp Design rely on an integrated heat sink and fan to provide adequate cooling for the amplifier
  • Dealing with Large Dynamic Range
    Designing an ultra-low noise, high speed, DC coupled amplifier that operates over a wide temperature range is difficult, but the technical problems become far more severe if the amplifier also has to function over a wide dynamic range. By wide dynamic range we mean that the amplifier has
  • Design and Development of Medical Electronic Instrumentation
    signals. Projects include a dc-coupled biopotential. amplifier with automatic offset cancellation, biopotential amplifier with dc rejection,. ac-coupled biopotential amplifier front end, bootstrapped ac-coupled biopotential amplifier,. biopotential amplifier with selectable RC bandpass filters
