The initial investigations were not very illuminating, until I realised that changing a component value in the typical power amplifier circuit very often alters two or more distortion mechanisms ...

This is a 35W audio power amplifier built with TDA2030 in a bridged connection with a +- 15V symmetric PS. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

NTT and Tokyo Tech have designed a power amplifier circuit 6 that achieves high-output power in the 300 GHz band and realized its fabrication by using NTT’s proprietary InP HBT technology.

A dual high voltage, high current, 1 MHz bandwidth amplifier with 1000V/μs slew rate boosts the power handling capability of a small signal, general pur- pose op amp.
