The distortion performance of an amplifier is determined not only by open loop linearity, but also the negative feedback factor applied when the loop is closed. In most practical circumstances ...

The OPA365 rail-to-rail input amplifier achieves rail-to-rail input swings using a charge pump to create a higher internal voltage for the input stage; in contrast to the more common method of using a ...

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...

Said to be the industry’s lowest power zero crossover op amp, the OPA369 from Texas Instruments achieves rail to rail performance without input crossover, solving the common design problem of input ...

Consumer demand for flexible audio features and hi-fi sound from mobile phones has led to handset audio chip designers having to optimise the Class D amplifier to meet the noise and power management ...

Krell announced the most revolutionary design change in its 33-year history: iBias, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less ...
