This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to ...

Designers are starting to use low-power, negative-swing-capable audio amplifiers to achieve higher-quality audio performance than was possible with traditional single ended amplifiers. These ...
