All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...

The previous two chapters considered closely the distortion produced by amplifier output stages: a basically conventional but well designed Class-B amplifier with proper precautions taken against the ...

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 ...

Input crossover distortion has long been the bane of rail-to-rail op amps. The input stage for most R-R amps consists of p-and n-channel differential pairs (Fig. 1a). The result is that the stage's ...

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 ...

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 ...

At CES 2016, Bryston introduced its new Cubed Series lineup of solid state power amplifiers, replacing the award-winning Squared Series (SST 2) that made its debut at the 2009 CES. The Cubed series is ...
