Audio Amplifier

Graphene audio voltage amplifier.

The main building block of analog electronics is a voltage amplifier: an electronic device capable of amplifying small alternating current (AC) voltage signals. Many graphene analog electronic devices, performing different functions, 1-5 have recently been proposed stemming from high carrier mobility 6,7 and ambipolar transport in graphene field effect transistors (FETs). However, none of these...

Boost bridge audio amplifier

The main difference in topology of a boost bridgeamplifier and state-of-the-art class-D amplifier is in theconnection of a loudspeaker between a power supply and aswitching bridge. The boost bridge amplifier provides fourtimes higher peak power at the loudspeaker than the power,which can be achieved by a class-D amplifier from the samepower supply. Total harmonic distort...

15-20W Class AB Audio Amplifier

Many class B designs can be operated in class A at low power levels if the quiescent current is increased. However, this often worsens the distortion characteristics of the output stage, particularly at intermediate (and audibly important) power levels, by displacing the crossover point to a region where the transfer slope is much steeper, and the crossover discontinuity therefore much more pro...

Comments on Audio Power Amplifier Design Handbook

Douglas Self’s writing on audio power amplifiers provides the reader with invaluable information. Not only does he teach the fundamentals (and details) of power amplifier design per se but also discloses a systematic approach to analyse the distortion performance of typical amplifier topologies. The latter is particularly important as systematics does not appear to be a natural thing in audio c...
