| Abstract |
This paper presents the derivation of a practical solution for constructing a signal tracking power supply for single-ended switching audio amplifiers, motivated by requirements for reduced EMI. The cause and effects of ‘supply pumping’ in single-ended switching amplifiers are
investigated, and simulation results for a power supply to meet the specified demands are presented, as well as the results obtained from the constructed prototype. |
